Hi Gerry,

no, there is no such mechanism available since it's not reliable - for example, during a call, more TCP connections may be used - one for the INVITE, close the connection during the call and open a new one for BYE - it's perfect possible, so you cannot rely on the transport status.

there are other ways to do it - at signalling level, via Session Timer; at media level - see when no more RTP traffic comes form one point.

regards, bogdan

Hi,

Is there any functionality implemented in SER/Openser which allows to detect dead endpoints ?

Gnugk implements this with tcpkeepalive timeouts. Is there any equivalent or something similar in SER which would prevent non-active calls to hang - and incurr possibly large costs ?

TIA for your help in the matter

Gerry
