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
International Calls As National" (page 183)
configuration of this feature and an illustrative example.
