Imagine the TCP case: - UAC sends a INVITE from IP_A:PORT_55555 with "Via: hostname_A". - After receiving the INVITE that connection hangs up because a network failure. - UAS try to reply but since the connection was down it MAY try to send the reply to any address that "hostname_A" resolvs (SRV, NATPR...). -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
