Mapping SIP headers to call-control properties

This functionality specifies rules that describe which SIP header should take place as a specific call-control property like the called-e164 or the calling-e164 number.

Configuring ISDN Redirecting Number Tunneling Over SIP

A SIP interface can be configured to tunnel the ISDN Redirecting E.164 Number and Redirecting Reason. This is implemented per the IETF draft standard method according to draft-jennings-sip-voicemail-uri-05.

The figure below shows a call that is redirected in the PSTN network and reaches the device over an ISDN interface. The incoming ISDN SETUP message contains additional information elements for the Redirecting Party Number (B) and the Redirecting Reason (Call-Forwarding-Unconditional, for example). When the Redirecting Number Tunneling over SIP has been enabled, the Request-URI of the outgoing SIP INVITE message has additional parameters for the redirected number (target) and the redirecting reason (cause).

Normally, the Redirecting Number Tunneling over SIP is disabled. However, you can manually enable this fea- ture for each SIP interface separately using the following commands. Note that transmission and reception of the target and cause parameters must be configured separately.
