[SR-Users] Prevent missing BYE request

Hello Alex,

Thanks for your reply.
I had a look to the timeout signalling socket. Looks to match the need. Do
you know what is intended by "a media stream timed out."? How the timeout is

Indeed, SIP Timers would be the better way and full SIP based. But this
suppose that all the endpoints support SIP Timers. I cannot guarantee this.

Dialog seems to do the job also with "default_timeout" parameter.

It's not necessarily easy, since SIP proxies do not, by their very nature,
lend themselves to this sort of thing, but rtpproxy does have a timeout
signaling socket:


But honestly, you'd be better off with a purely SIP-based method of dead
peer detection, be it making the endpoints use SIP Session Timers, or using
the Kamailio dialog module's OPTIONS-pinging method:
