Thanks, we'll certainly give it a try. Could you explain what this
patch does exactly?
If no RTP has been sent yet, wouldn't stats->recv be 0, and
audio_stream_alive() always return TRUE?
Thanks,
Dan
if stats->recv = 0 like stream->last_packet_count (when audio start or
payload change _reset_rtp_alive_info() set last_packet_count to 0 and
last_packet_time to "now")
So, if there aren't any packets after timeout+1 seconds become:
!(stats->recv!=stream->last_packet_count) &&
(ms_time(NULL)-stream->last_packet_time>timeout)
=> return False
Is it OK?

Hi Dan,
try this patch... I write it on the fly (without compiling :) )
I think it should work. I wrote a patch like this for an old
linphone version.
I hope it works and fix your issue.

Thanks for the response Simon.
The RTP timer seems to work great as long as it has received at
least one RTP packet for the session to start the timer, but if
the incoming call silently terminates before RTP has started, the
call remains up indefinitely, which is why I was looking for a
SIP session timer solution. Is there anything else I could try?
Thanks,
Dan

Hi Dan,
Actually what is implemented when use_session_timers=1 is
accepting SIP
updates and answering correctly to them, but linphone does
not send any
SIP update or reINVITE to check the session is alive.
However it detects loss of RTP streams, after 30 seconds of RTP
inactivity (RTP and RTCP), then it hangups the call.
