Hello,
When using TOPOS module, Kamailio add this header :
P-SR-XBranch before executing the topos module.
Doing this “remove_hf_re("P-")” in the scripting seems to bypass the addition of the P-SR-XBranch in the sip message.
In my mind, remove header function just remove the headers based on the incoming message.
What do you think ?
