Hi, users.
Sorry about my poor english.

 

I am a beginner of FS.

I have a problem with IP-PBX.

My customer wants to call mobile phone using FS connected IP-PBX.
IP-PBX must set 100-rel mode.

 

IP-PBX send to FS with custom SIP header(P-Charging-Vector), and I want to add this header to response SIP message.

 

I read FS wiki and try many cases. but, i can't solve my problem.

 

Follow is my call diagram:

 

=======================================================================================================
SIP CLIENT    :  FreeSwitch             :         IP-PBX  :         Telecom(?)
=======================================================================================================
INVITE -->
                <-- 100 TRYING

                        PRACK --> (without P-Charging-Vector  Header)
