[SR-Users] ack with cscall-id header

[Daniel-Constantin Mierla]

Hello,

if you cloned the kamailio source code from the git repository, send the
output of 'git diff' -- that makes it easier to understand the changes
you did and spot if there is any error.

Cheers,
Daniel

Now instead of routing the Bye to the sip phone, I want to create a re-invite request from kamailio and send it to the sip phone. The purpose of the re-invite is to connect the sip phone to another sip phone that already has an active call. This part is working fine but the problem occurs after the sip phone sends the ‘200 OK’ message for the re-invite. Kamailio sends an ACK for the 200 message but this ACK has a ‘CSCall-id’ header instead of the ‘Call-id’ header.

In the uac.c file found in the tm module folder, I added 2 lines of code to the request function in order to stop the UAC module from creating a from tag(attached). I also attached a trace that shows the ack message with cscall-id.
