Hi everybody, i dont seem to be able to get the force_tcp_alias to work ... or i am using it for the wrong thing. I want ser to reuse tcp sockets. My config is: phoneA ---UDP---- SER_A ---- TCP ---- SER_B ---- UDP ---- phoneB Now, if phoneA sends the INV to phoneB, no problem. If phoneA hangs up, SER_A reuses the tcp socket to send to SER_B. But, if it were phoneB to hangup, SER_B does not reuse the tcp socket it already has with SER_A. I've tried calling force_tcp_alias on top of the config file ... but no luck. Any ideas?
