Update, manually modifying the To-Domain in ACK has fixed this, I saved the
key value pair Call-ID/To-Domain of 200OK from CISCO and for corresponding
ACK with same Call-ID modified the $td
same problem appeared in BYE for the call, again same fix by modifying the
To-Domain for the same Call-iD in subsequent BYE.
QUESTION: Was this supposed to happen with mhomed Kamailio ? I have not
observed this scenario with any provider/gateway other than this CISCO gw!

Sammy.

Yeah sure, attached here is the trace from the CISCO
logs. Not in pcap
format.
Also this is the flow of the call.

Is the UAC in this case a 2543 endpoint by
chance? Can you send a
complete SIP trace of the entire setup?

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.
Best Regards,
Sammy.
