ISDN Interworking Redirection


ISDN Interworking Redirection takes the incoming ISDN message and interworks it to SIP signaling on the outbound side so the 'Original Called Number' can be identified on the SIP side. This information will be passed in the SIP Diversion Header. If diversion headers support is enabled, the information contained in the diversion headers will be translated into two different information elements in the ISDN SETUP message.
