I've been choosing the SIP client for my live distro and, after quite a bit of 
testing, has finally stopped on Linphone as most balanced solution for A/V 
calls. Unfortunately, I have to maintain my own builds but so far there is no 
better way. However, recently I recommended Android version of Linphone to a 
friend and we decided to test encrypted A/V calls between Android and desktop 
versions. Here's what we found:

* No sound was heard from his mobile with any settings while it were surely 
transmitting. We didn't try connecting headphones but it shouldn't require them 
* Video resolution settings are hardcoded and limited to measly 720p which is 
his front camera resolution. WHY ? What if he would want to transmit realtime 
video of something from his proper, rear camera via his high-speed WIFI/fiber 
connection ? What about bitrate ? Even 720p from front camera looked all choppy 
and squared-out. It definitely didn't utilize available network bandwidth. And 
are there any plans for VP9/webm ?

Also, no one still answered my previous question about possibility of JACK 
support (right now I'm using PulseAudio as JACK client) and Linphone has no 
active bugtracker (devs ignore the old one) where these questions really should 
be going.
