Hi, I'm sure there are a lot of discussions about it here, so don't shoot me on this.
What must be Contact address if SIP client is behind NAT and it uses TCP or SSL ? The problem i see: SIP server never can't establish connection to SIP client, so server must use active TCP connection. No problem with that, but again Contact here turns to be useless in that case. With UDP simple, you STUN public IP end point and use it in contact ... . Any comments are welcome. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
