Add SDP info to INVITE Message using HMR
Hello team,
I need some assistance on adding sdp information to an INVITE message using a header rule. I know you can add it using the add-sdp-invite option for that particular sip-interface, but need to also enable the rfc2833-mode to dual to transcode inband dtmf to SIP-INFO. From what I read, you can only do sdp manipulation or rfc2833 modes but not both.
The header I created is below, but I only get one line in the response which fails as a valid sdp message.
