Dear support,

I''m trying to encapsulate my private "application/isup" in the SIP Msg. Normally, it should like below example.

It firstly addresses "Content-Type: multipart/mixed;boundary=QRLVLNKeKxWDHAuwlEkR". And then can write private "content-type" like "application/sdp".

Now I can see the application/sdp is encapsulated via variable "switch_r_sdp".

Is there anyway to encapsulated other customized "content-type"?

Appreciate to get your reply.

Here is an example of SIP message which encapsulated "applicaiton/sdp" and "application/isup".

INVITE sip: 87896677@dance.com;user=phone;SIP/2.0
