SIP Trunk E.164 CLIP Enhancement

With the SIP Trunk E.164 CLIP Enhancement enabled, when an incoming SIP call from an external ITSP

is presented at the system with a + in the From header field as the international access code, it is

recognized and displayed as an international call at the terminal display and also logged in the terminals

incoming caller history, allowing any outbound calls made from a multiline terminals caller history

possible using this numbering scheme.

This presentation can be a requirement of certain SIP ITSPs (Internet Telephony Service Providers) so it

is necessary the PBX can handle these calls and modify any SIP messages to the correct format

accordingly.

E.164 Enhancement is applied for the SIP trunk interface.

Outgoing call from caller history of incoming calls is only possible from multiline terminals.

Netlink systems deployed in multiple countries using this feature may not work correctly

because the system will not know which international code should be added at each node.
