[Users] Zombie/hanging calls - TCPKeepalive timeout possible ?

[Bogdan-Andrei Iancu]

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
