Hi All,
I met a problem with SIP over TCP on chan_sip driver:Network setup:
Client in public internet.
Server behind the router is reachable through port forwarding.
Customized sip server port is used (not 5060).SIP client from public internet registers successfully but can't make calls -- call gets interrupted in 6 s after answer with the "no reply to our critical packet" warning. This happens only over TCP and over UDP all OK.
After some investigations I found a difference in 200 response on INVITE:
over TCP the port in Contact is 5060
and over UDP this port is my custom value.
So then over TCP the server can't receive an ACK on answer and call gets dropped.Seems like no such problem for pjsip.
Did any one meet this and resolved, appreciate any ideas. Thanks!
