I need to set SIP header after receive response to INVITE with 4xx code.
I work in 3PCC mode and with SU 395
When i receive this code, i call gc_dropCall and HMP send automaticaly ACK paquet. I need to set "Via" header and "User-Agent" header.
I tried a lot of combinaison with gs_SetUserInfo, but nothing work.
Maybe someone found a sequence that works.
Thanks in advance
I have a problem with the Ack response of an redirection response (302).
HMP send Ack without "VIA" header.
I don't know how can i do to set VIA header before gc_dropCall.
Can you provide the full SIP message flow in this case in order to comment further. When exactly do you get the 302?
