Hello guys! Sorry for desturbing you, but maybe someone know, how i can fix this problem on Cisco SIP phone 7940:
1) Cisco SIP phone received 200 ok with Contact like:
Contact: <sip:1.1.1.1;did=TUFgRzw2JH97fHt4eXp3en53bRR0dXdtfnt1b3pxYVDJhjkfhhsdfJBNVsadgdsfdhgewh-> 2) Cisco SIP phone send ACK with R-URI like:
Request-Line: ACK sip:1.1.1.1:5060 SIP/2.0

Parameter "did" lost in R-URI, and ACK can not pass topology_hiding_match() properly.
Maybe anybody know how this problem can fixed from phone side?
Many thanks!
