News from Industry

Two messaging services. Focused on consumers. Doing practically the same thing. Do they compete or cooperate under Facebook’s roof?

Messenger and WhatsApp are the biggest messaging platforms toady. Messenger announced 800M monthly active users recently, while WhatsApp celebrated hitting the 1 billion mark. As they both strive to continue with this rapid growth, I have to question – are they joining forces or competing fiercely between themselves.

The reason I raise it stems with how they implemented web support and VoIP:

• Messenger unbundled from Facebook, opening its own independent site, which acts as a full messenger client. If you want to make calls, you use WebRTC for that
• WhatsApp created a web frontend tethered to the phone app. It cannot work without the phone nearby. And when it comes to VoIP, it might be using the same codecs as WebRTC, but not the vinyl implementation

They are taking different architectural approaches. But they end up implementing the same feature set.

WhatsApp in 2015

Here’s what WhatsApp did or was rumored to be working in the last year:

• Experimenting with video calling
• Planning to introduce tools for businesses to communicate with users
• Adds voice calling
• Introducing WhatsApp web

Messenger in 2015

Here’s what Messenger did in the last year:

• Facebook adds video calling to Messenger
• Unbundling Messenger from Facebook accounts – rely on phone numbers
• Unbundling Messenger from Facebook
• Introduced Businesses on Messenger
• Other notable additions include Transportation, sending money

 

Not much of a difference…

Running such a thing at scale of 100’s of millions of people is painfully hard. Doing that twice under the same roof is even harder:

• It seems like they develop everything twice or separate infrastructure and architecture.
• There’s no federation between the two – you can’t send a message from a Messenger user to a WhatsApp user – even though both belong to the same company

Where would each of these services go next for growth?

The above slide from eMarketer shows how in some countries, the main competitor of WhatsApp is Facebook Messenger – and vice versa. I think each of them tries independently to raise his users base – with no real regard of the other’s footprint at any given location.

This one from Activate goes to show how growth for both these platforms come from the same areas – and where they overlap or compete on the same set of users.

–

Something doesn’t work out here for me, though it is hard to lay a finger on it.

WhatsApp is probably still a strange bird in Facebook, far from the rest of the company and its DNA. Getting it in line with Facebook will take considerably more time.

Probably not.

I wrote about Peer-to-Peer and WebRTC recently, and got this interesting question due to it from Fabian Bernhard on LinkedIn:

Without arguing about the quality of a specific Open Source media stack, would you say that WebRTC was as big a thing if it didn’t run in a web browser?

I guess the answer is no it wouldn’t be that big a thing.

Here’s where I am getting at it. There are two popular slides I usually use:

The one above explains that WebRTC sits at an intersection – it appeals both to VoIP people as well as to Web people.

The second slide above is about what makes WebRTC so transformative – it is about the fact that it is Free, but also because it is available for Web people.

Without the web browser part, we would have been left with only Free.

We’ve had open source media engines before. GStreamer is a popular one. Codecs were a bit harder to come by – especially those that don’t require patent payments (royalty free). It wasn’t the best thing out there, but it worked – people still use it today.

WebRTC made the open source version of a media engine as good as a commercial one – it came out of an acquisition of a commercial media engine vendor after all.

But that’s where it stops – it wouldn’t have made such a transformation in the market – it would be more of the same with a small evolutionary step. Nothing to write home about.

The browser bit, though… that made VoIP available and open to everyone with some HTML and JS experience – a lot larger pool of talent – and one dabbling a lot in experimentation. This is what got us so many use cases.

Mobile might be different

For mobile only use cases, WebRTC would have made all the difference – same as it does today. The idea behind it in mobile isn’t that it offers a browser experience or that it is available in the browser (it isn’t on iOS). The idea is that it would have been the cheapest route to a product than anything else out there. And with the trend of communications moving in-app, that would still make the impact it does there relevant.

Which brings us full circle.

Let’s assume mobile is eating up the world. Let’s assume it is only a matter of time until content creation and not only content consumption moves from the PC to mobile. Once that happens – who cares about what happens in the browser?

It will all be in-app anyway.

And there – WebRTC is making a difference.

This week we had the addition of a real-time counter for calls in a queue. And in other news we would like to thank everyone that contributed to supporting the FreeSWITCH developers during their summit! They were able to make some exciting progress on some much needed planning and syncing thanks to your support!

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! This week we have Jun Sun from Netspectrum! And, head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8822 [mod_callcenter] Added a real-time counter for calls in a queue

Improvements in build system, cross platform support, and packaging:

• FS-8808 [core] Fixed ^D in fs_cli with editline to delete char under cursor, not just backspace
• FS-8818 [core] Refactor X-PRE include to not toss error if there are no files that match the include

The following bugs were squashed:

• FS-8812 [core] Respect in_thread_only parameter in switch_channel_check_signal()
• FS-8809 [core] Fixed an undeclared MAP_POPULATE causing compliation failure
• FS-8816 [core] Fixed switch_core_hash_insert_destructor not checking switch_hashtable_insert_destructor() returns
• FS-8821 [core] Added checks for status of executed operation
• FS-8830 [core] Added SDP line separator fix for SDP generated by the core. Sofia when giving an SDP through SOA was parsing the SDP and rewriting it. For endpoints that use the core SDP as is will have more accurate SDP now.

Wondered how you can quickly start your own IMS platform? Thanks to Franz Edler, from University of Applied Sciences, Vienna, Austria, a set of configuration files as well as a WMware Debian image were made available for those that want to start building an IMS platform using Kamailio. Read this documentation written by Franz (original version in pdf format can be downloaded from here)!Kamailio IMS in a BoxHere is a stripped-down version of Kamailio-IMS system – it means that the IMS functions have been reduced to the core functions, all advanced functions like NAT, RTP-relay, antiflood, capturing, dispatching etc… have been omitted (disabled). It is a good starting point for educational purposes. All three servers (P-CSCF, I-CSCF and S-CSCF) and the HSS (from original Fraunhofer OpenIMScore) are running on one machine. The clients are typically provided by the host system.The additional functions which are included in the existing config-files are disabled in a first step and may be added (enabled) gradually. Also an application server (IMS-AS) may be easily added as a further Kamailio instance. This is perfect for educational purpose, if you want to become an IMS expert.The benefit is that all these servers and function are running on one physical machine. There is a VMware image available for this configuration and also the log-file and all relevant config-files in a separate zip-file. Now you can start immediately with the VMware image or – as I always suggest – do it yourself (compile and configure) by following the steps documented in the log-file.The figure below shows the configuration I used:All parameters and passwords used are documented in the log-file.If anything is missing or if you have hints for correction or improvement, just let me know via the sr-users@lists.sip-router.org mailing list.All files are available via dropbox:

• The VMware image:https://www.dropbox.com/s/pwwx009hiigt27v/Debian_8.2-step5-basicKamailio%26basicIMScore.zip?dl=0
• The log-file and the config-files: https://www.dropbox.com/s/ehkzi9pbhlp7njc/Kamailio-IMS%20config-files.zip?dl=0

Good luck, FranzNR: the version above was slightly edited for web and few more explicit details.Read previous articles about Kamailio and IMS!If you build some specific systems using Kamailio and want to share the details with the community, do not hesitate to contact us, we will be more than happy to post an article about it on Kamailio web site!Thanks for flying Kamailio and looking forward to meeting many of you at Kamailio World 2016!

The Call Center World 2016 trade show takes place again in Berlin, during February 22-25, 2016.


While not directly linked to call center solutions, Kamailio SIP Server is often deployed along side a call center system to add more flexibility in SIP routing, redundancy and perform SIP firewalling.

Not too big, but not small either.

Here’s a shocker – Facebook Messenger has been updated 19 times on Android in 2016. WhatsApp has had 25 releases in the same time span. And we’re not even in the middle of February.

We are talking about the two messaging applications with the largest number of monthly active users, with WhatsApp surpassing the one billion milestone. gulp.

Should we place messaging apps under weight watchers?

To deliver an app that weighs 26 MB to a billion people (I am thinking WhatsApp here), you end up sending over 23 petabytes of data (translation: a shitload of bits). Doing that 25 times since January 1st…

I took a stab at looking into the consumer messaging apps (some of the enterprise ones are larger, though less frequently updated). Here’s what I found:

#1 – They are all fattening up

The scatter graph above is a bit scattered, but it is easy to see that most apps are increasing in size over time. Since September 2014 until January 2016. They all migrated from the 10-20 MB sizes into the 20-40 MB sizes. That’s a doubling in their weight in less than two years.

We don’t think about it much, but we’re in a serious need of a diet here:

1. This loads our networks. Not as much as video traffic, but still significant
   • Most users have more than one such app on their phone
   • These apps update frequently
   • It adds up
2. With WhatsApp reaching the one billion mark, where will it be headed next?
   • To maintain its growth it needs to search for additional users
   • These need to come from developing countries
   • And there, bandwidth and data is scarce
   • The smaller the app, the easier it is on users to handle
3. Most of the messaging apps don’t seem to care about how fat they are

#2 – Size doesn’t equate feature richness

The bar chart above shows how big the latest version of each of these messaging apps is.

Te results are rater surprising:

• Skype is the bloated of them all at this point in time, but I don’t remember anything new or interesting that Skype on Mobile introduced in the last two years. And yet – it managed to double its size
• Those in the vicinity of one billion users/downloads are trying to stay on the skinny size – Facebook Messenger, WhatsApp and Hangouts are all rather small compared to the rest of the pack – and somehow, Facebook Messenger is even smaller than WhatsApp (I’d expect it to be the opposite)
• WeChat and LINE, which can be seen as e-commerce platforms are larger than most, but somehow Skype and Viber manged to be even bigger

–

I wonder when a diet will be called for. And maybe it already is.

Back in October 2013,  the relative early days of WebRTC, I set out to get a better understanding of the getUserMedia API and camera constraints in one of my first and most popular posts. I discovered that working with getUserMedia constraints was not all that straight forward. A year later I gave an update after the […]

The post getUserMedia resolutions III – constraints unleashed appeared first on webrtcHacks.

If you aren’t using AppRTC yet then you should start.

I had a few customers last month who had quality issues with their service. They were trying to understand the root cause of these issues, and at times, the question raised was “is WebRTC up for the task?”

• Does the poor audio quality we experience in our service derive from the codec, the browser’s implementation or something in our own backend?
• Are the video stutters stem from heavy packet loss and that’s just life – or are we adding some of our own issues into the mix?
• The average bitrate we reach in a call. Is it because the browser is limiting us? Is it because the connection is bad? Is it…

The list goes on.

The fact that now you get a fully implemented media engine in the browser for free is great. The problem is, it gives you (or your developers) the opportunity to blame the browser: It isn’t us. Google’s engineers did such a crap job with X that we just can’t fix it.

More often than not – this won’t be the problem.

When in doubt – check AppRTC

Google launched AppRTC quite some time ago.

AppRTC is Google’s way of showcasing WebRTC in their simplest version of the “Hello World” program. This being WebRTC, there are many moving parts, but to some extent, AppRTC is rather baseline – especially in its dealings with media.

This makes AppRTC a great baseline reference when you have issues with the media paths of your own service or just want something to compare it with.

Got an issue? Test what happens when you run AppRTC and compare it with your own service. If you see that your service isn’t performing in the same manner, chances are the problem is on your end – and now you can start diverting focus and resources towards searching the problem instead of blaming the browser.

Where to look for the problems?

• Your NAT traversal servers, if they are being used
• Are you doing any backend processing for the media? Map your pipeline there. Check each step of that pipeline to see if it is to blame
• Transcoding never fails to fail you – check there if you use it
• Jitter buffers are notoriously… jittery. Make sure the implementation fits your use case
• Network routes and handling dynamic bitrates and packet losses might be handled nicely by the browser, but is your backend up for the task as well?

Don’t forget test.webrtc.org either

Google has another great analysis tool – test.webrtc.org

You open the settings, insert your own STUN and TURN server configuration – and start the test.

It will then check the system and network connections to give you a nice view of what the browser is experiencing – something you can later use to understand the environment you operate in.

Why is this important?

With WebRTC, it is easy for developers to blame the browser. This isn’t productive.

Your first task should be to create a baseline reference you can trust. One that enables isolating the issues you are experiencing systematically.

AppRTC is a good place to start.

Our next Kranky Geek event is taking place in India.

Kranky Geek events? We did them twice. Both times in San Francisco. Both were very successful events. In both we didn’t know if these are one time gigs or something we want to continue doing.

Then we sat down to plan 2016, and came up with three planned events. The first one is taking place in Bangalore, India.

As with any Kranky Geek, this one is about developers of real time communications.

Like previous Kranky Geek events, it is free to attend. Sponsors take the burden of enabling us to plan this event and then pay for everything around it.

Google has been taking the lead here and helping us a lot in getting these events off the ground – in a way taking the leap of faith in our ability to manage these events.

India

Google asked us to do an event in India, so we happily obliged. For me, it would be the first time in India, making the excitement on my end even higher.

India makes sense in a lot of ways. Many of the vendors I end up looking are vendors that are local to India. Others are vendors with large development teams in India who end up doing a lot of the WebRTC development. Kranky Geek India gives me personally a great opportunity to meet many of these people in person.

To make things short:

Where? Bangalore, India

Exact location: MLR Convention Center

Date and time: March 19, 11:00 until we finish

How do I register? here

 

Our sponsors this time are Google, TokBox and IBM. Expect a large cadre of interesting speakers and topics – some local and some international in nature.

I’d love to see you with us at the event!

The development (master) branch of Kamailio enters now in pre-release phase for version 4.4.0. Therefore, no new feature are going to be pushed to master until a dedicated branch for 4.4 is created (in about 4 weeks or so). The full release should be out by mid of March 2016.If you are a registered developer and in doubt to push or not a commit to master, push it first on a personal branch (or attach to an email) and discuss it on sr-dev. The new modules can be a bit more dynamic if there is need to get them to the right shape (e.g., like decision to rename functions, parameters or adjust database structure).We hope to get many people involved in testing, to reach a stable state before releasing 4.4.0. If you want to get involved and need assistance, don’t hesitate to write to mailing lists. Based on my quick review, there were no major changes to old core components, meaning we should have preserved quite a good level of stability overall.Help with updating the wiki page for migration from 4.3 to 4.4 as well as what is new in 4.4 is very appreciated. We will post updates about them very soon.Many thanks to everyone involved in development of 4.4 and the early testers that played with master branch so far.Thank you for flying Kamailio!Looking forward to meeting many of you at Kamailio World 2016!

Just making sure you’re not missing out…

If you don’t know, in the last year I’ve been part of a great team of partners. We are building together a WebRTC monitoring and testing service called testRTC. The service is up and running for some time now with an increasing number of customers.

The most crappy part of our service was our website (not the one customers are using, but rather the one potential customers look at). So we updated it recently.

One of the main additions to that website is the new blog there. I’ve got an editorial calendar for it running until March with weekly content that I want to share with you, but felt that BlogGeek.me isn’t the best of places for it – it was too focused on testing or too related to testRTC.

What will you find in our testRTC blog?

• Announcements about our service and the versions we are rolling out
• Useful tips for testers, like the one we published yesterday about .y4m files and Chrome
• Things we think you should take care of in your testing practices
• Insights into our design decisions for our internal architecture
• Test script samples of how testRTC can be used to handle certain WebRTC testing issues

So some of the content will be relevant to everyone while other parts of it for those using testRTC.

Dumb pipe or not, data services thrive mainly out of the telecom world these days.

Can Telecom Services survive the Internet?

Telecom Services are an interesting notion. For over a hundred years we’ve been taught that Telecom Services=Phone calls. Then messaging was added to it in the form of SMS on mobile. Telecom services themselves assume that their role in life is to sell us our communication services.

This is no longer true.

I remember working on 3G-324M. A circuit switched video protocol, now dead to the world at large. In many of my discussions, people complained about their inability to add services on top of what a carrier provided – there were too many layers of debilitating bureaucracies.

Today? Everything operates over an IP network. Most of us don’t even care if it is cellular, landline, wireless, or whatever – as long as we get our bits on the line – we’re happy.

While we are all happy using VoIP services and discussing how disruptive it is to carriers, we haven’t seen nothing yet.

The wheel has turned. In the past, advantage lay in owning the network and offering managed services on top of the network. Today, and moving forward, advantage lay with those who can operate their service across networks.

This means that carriers are left with their own network, and a DNA of working inside their own managed network – something that makes it harder for them to operate in this new reality.

Here are two areas that drive the message home:

#1 – Google Fi

Google Fi is how mobile phones should operate. It is Google being an MVNO and offering mobile plans to its customers. Instead of buying a plan (and maybe a subsidized handset) from a carrier, you can just purchase a plan from Google – and use a Nexus smartphone.

What makes Google Fi so different is that it operates on 3 different networks:

1. Sprint
2. T-Mobile
3. Any Wi-Fi it can get connected to

Read the FAQ for this one – it is quite telling.

Here’s one piece of it:

What happens if I start a call over Wi-Fi and then lose my Wi-Fi connection?
On your Project Fi device, if you start a call over Wi-Fi and then your connection weakens or drops (such as when you leave your home or office), Project Fi seamlessly transitions your call to a cellular network (if one is available) so you can keep talking.

Calling is no longer tied to a cellular network. Fi has 2 cellular network and whatever Wi-Fi you happen to be on. And it decides what to use based on past experience of Google – and is able to change that dynamically mid-call.

Fi is not your typical MVNO. Or your typical VoIP provider. Or your typical carrier.

It is just how things should be.

#2 – Internet of Things

The Internet of Things to me is everything but a carrier. The hint to that is in that first word – Internet. You don’t really need a carrier for that – just an IP connection. Any IP connection.

While there are use cases that will necessitate a carrier (or just his SIM cards?), most of them don’t have a carrier as a prerequisite for their existence.

I like this slide of Octoblu – an IOT platform that was acquired by Citrix:

It shows the various players in the IOT space:

• IOT frameworks
• Smartphones (control points of us humans)
• Embedded devices and sensors
• Messaging, aggregation and rules engine for all the data flowing around
• Storage and analytics
• Applications and integration

Nothing about the underlying network. No one really cares what that ends up being. Which makes sense. For this to work, you need an ubiquitous network. Not necessarily one with high bandwidth or no packet loss – but one that you can assume exist. Which is what we have in most of the modern world now.

Final Thoughts

No. This isn’t the end of carriers.

Yes. They will still make boatloads of money.

Much like electricity is a utility, access to the Internet is a utility.

The services on top of it though? They don’t necessarily belong to the carriers.
