What steps will reproduce the problem?
1. Install asterisk 13 using the following guide: 
https://kunjans.wordpress.com/2015/01/09/web-sip-client-sipml5-with-asterisk-13-
on-centos-6-6/ 
2. Use PJSIP as the sip driver, and allow alaw,ulaw,vp8
3. Login with 2 endpoints on SipML5 demo

What is the expected output?
When the call is answered, there is audio and Video flowing.

What do you see instead?
On Chrome I get call terminated when anwering it, and i see this errors in the 
Asterisk logs:
WARNING[1844][C-00000010]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect 
failed with: authentication failure 10
WARNING[1844][C-00000010]: res_srtp.c:407 ast_srtp_unprotect: SRTP unprotect 
failed with: authentication failure 110

On FireFox, only audio is working, but the call works without errors.

When I call from a zoiper client, to a SipMl5 endpoint, I see video from SipML5 
on the zoiper client. But not the other way around.


What version of the product are you using?
I use the demo of SipML5 r230

On what operating system?
Windows 8.1 64 bit

On what browser:
Chrome 41.0.2272.101 m
FireFox 36.0.4

On what native client:
Zoiper 3.6.25251

Please provide any additional information below.

I have used all kinds of patches, like the opus vp8 patch. But this didnt work 
either. It looks like the video stream doesn't add into the html of SipML5.

With working accounts from OnSIP it doesnt work either, only audio. But when I 
use JSSIP with OnSIP I have audio and video. That gets me thinking that de 
video of SipML5 is broken?
