Re: [SR-Users] Multi-homed Kamailio Modifies ACK

Is the UAC in this case a 2543 endpoint by chance? Can you send a complete SIP trace of the entire setup? -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry. *From: *SamyGo *Sent: *Tuesday, May 12, 2015 11:46 *To: *SIP Router - Kamailio (OpenSER) and SIP Express Router (SER) - Users Mailing List *Reply To: *Kamailio (SER) - Users Mailing List *Subject: *[SR-Users] Multi-homed Kamailio Modifies ACK Hi all, I'm having a scenario where I'm sending call to CISCO IAD2431. The call establishes with 200OK from CISCO and Kamailio sends back modified ACK. Cisco at this points gives out an error and sends 200OK again, Kamailio replies with ACK, and this cycle goes on until the call drops. Here is the error from CISCO: Failed FROM/TO Request check old_from: "Test Phone" <sip:+14432232221@192.168.1.106>;tag=as370915fc old_to: <sip:+14444812211@sip.iamip.com:5041>;tag=9FEC572E-100F new_from: "Test Phone" <sip:+14432232221@192.168.1.106>;tag=as370915fc new_to: <sip:+14444812211@192.168.1.244:5041>;tag=9FE I've #auto_aliases=no and, listen=udp:44.33.22.11:5041 listen=udp:192.168.1.244:5041 Kamailio sends INVITE through the Public IP to the CISCO gw, but decides to change the ACK header. Any advise please.
