You can set "hardcoded" branch values.
For example: Invite's Via-Branch= z9hG4bK-[call_number].
Since CANCEL has the same Via-branch as INVITE set it to
z9hG4bK-[call_number] value too.
This way for each INVITE sent you will have its own uniqe Via-branch and
every CANCEL will have Via-branch correcponding to INVITE being canceled

Subject: [Sipp-users] suppressing the auto-creation of "branch"
Hi all,
how can I suppress the auto-creation of SIPp var "branch"?
(btw. param -nd is used)
In my testcase a INVITE should be canceled after a short pause:
INVITE sip:[servi...@[remote_ip]:[remote_port] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
.....
CANCEL sip:[servi...@[remote_ip]:[remote_port] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
That is still the 1st transaction but SIPp sends a CANCEL request whith
a new branch!
To fix the problem:
I grab the last branch value within the 180 response and use it for the
next CANCEL:
<action>
<ereg regexp="branch=(.*);*" search_in="hdr" header="Via"
assign_to="6,6"/>
</action>
CANCEL .... branch=[$6]
Thanks,
Wolfgang
