Hi Experts. I'm testing PGW 9.6(1).
Is there a way to enable SIP-GTD support in PGW, only for incoming SIP messages?
In my scenario, the PGW should honour the incoming SIP-GTD messages but not should generate outgoing SIP-GTD messages (only standard SIP).
e.g.
INVITE SIP-GTD (Content-Type: multipart/mixed application/sdp + application/gtd) ---> PGW 9.6(1) ---> ISUP IAM
ISUP IAM ---> PGW 9.6(1) ---> INVITE SIP (Content-Type: application/sdp)
I've enabled these parameters on incoming SIP trunk only:
ISUP Transparency Disable: Disable
GTDCapTypeProp: ALL
ISUPTransEarlyBackwardDisable: Enable
sipMimeBodySupport: 2
In this way PGW handles correctly incoming SIP and SIP-GTD messages but adds GTD headers in outgoing 180,183 and 200/SDP messages.
Regards.
