2. Programmable Media Platform The Programmable Media Platform SIP interface is described in more detail in the following topics e Inbound calls e ISUP to SIP cause values e SIP to ISUP cause values e VoiceXML exit information e BYE reason header e Call transfer Inbound calls An inbound VoiceXML session is initiated through a SIP INVITE The SDP Offer Answer model RFC 3264 is used for media negotiation The INVITE usually contains the offer and the 200 OK response contains the answer SDP The following table lists the possible responses to the SIP INVITE 152 SIP interface Response Description 200 OK Success 480 Temporarily Call not authorized Unavailable 503 Service Unavailable No channels available to take call By default the Programmable Media Platform handles incoming DTMF content in the following manner e If RFC 2833 is negotiated then the server obtains the DTMF tone and duration through an RFC 2833 DTMF event e If RFC 2833 is not negotiated then the server obtains the DTMF tone and duration from the body of the SIP INFO message If the joined connection is a SIP connection then audio transcoding automatically occurs between the two endpoints when required Variable mappings The following table lists the SIP INVITE components and the corresponding VoiceXML session variables INVITE component VoiceXML session variable INVITE Protocol Name session connection protocol name evaluates to
