SIP Content-Disposition: session; handling=required
Rating: +0
SIP -T uses multipart MIME bodies to enable SIP messages to contain multiple payloads (Session Description Protocol SDP or ISUP etc.) and we have the option of telling the terminating side that what support is required is it mandatory or optional
Content-Type: application/sdp // means that we SDP in enspacluaued in with the SIP packet
Content-Disposition: session; handling=required // this means that the terminating end needs to support SDP
like SDP , ISUP can also be packaged with a SIP
Content-Type: application/isup;
Content-disposition: signal; handling=optional; // this means that ISUP support is not mandatory
