  C. Content-TypE. message/ISUP

  Tunneling over SIP

  The Cisco gateway receives QSIG messages from the PBX side and then identifies the destination of the message (or call). The QSIG messages received from the PBX are encapsulated within SIP messages as Multipurpose Internet Mail

  Extensions (MIME) bodies and are sent (tunneled) across the IP network to the recipient gateway.

  When encapsulating a QSIG message (for switch type primary-qsig) inside a SIP message, Cisco gateways include the QSIG message in a MIME body of the SIP request or response using media type application/QSIG:

  

  Content-Type: application/QSIG
