SET HEADER SIP AFTER Response 4xx

  • Hi,


    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

  • H,

    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.

  • Hi,

    Can you provide the full SIP message flow in this case in order to comment further. When exactly do you get the 302?

    Regards,
