Hi,
I have tried to make a call from Firefox beta 23 to FreeSWITCH and SIP
phone connected to FreeSWITCH.
It works fine, thanks for the great work!
When calling firefox from FreeSWITCH or SIP phone connected to
FreeSWITCH, it gives me no audio.
After some investigation, i found that there is crypto tag in SDP from
freeswitch.
I guess it might be one of the reasons for no audio issue.
The logging ekr suggested will help. I *suspect* that when Freeswitch
initiates the call, it isn't properly handling answers without SDES
(a=crypto). Note: FF does not support SDES, only DTLS-SRTP, and we do
not plan to support SDES due to security concerns. Note: Freeswitch
must have support for DTLS-SRTP for calls initiated by Firefox to work,
but there may be a problem with them not properly handling the negotiation.
The logs will tell us more, as would any detailed logs available from
Freeswitch. You should also check with them.
