SIP INFO message

The TR/87 FE that resides on the Signaling Server contains a feature to insert the appropriate dial plan prefix, either national or international, depending on the location of the Call Server and destination of the call. This ensures calls within the country use the national dial format and calls outside the country use the international dial format. This feature is enabled or disabled in Element Manager in the SIP CTI Settings section. When “All International Calls As National” is enabled, any calls within the local country have the country code stripped from the E.164 number and the national dial prefix applied. The format of the number presented by the TR/87 FE to the Call Server through AML in this scenario is:

<SIP CTI national prefix><national subscriber number>.

Any calls outside the country have only the international dial prefix applied to the E.164 phone number. The format of the number presented by the TR/

87 FE to the Call Server through AML in this scenario is:

<SIP CTI international prefix><international number>.

When “All International Calls As National" is disabled, all calls to any E.164 destination use the international dial format. See section "Parameter: International Calls As National" (page 183) for additional detail on the configuration of this feature and an illustrative example.
