Version 5.8 129 September 2009
SIP User's Manual 3. Web-Based Management
Notes:
• Several rows with the same NPI-TON or Phone-Context are allowed. In
such a scenario, a Tel-to-IP call uses the first match.
• Phone-Context '+' is a unique case as it doesn't appear in the Request-
URI as a Phone-Context parameter. Instead, it's added as a prefix to the
phone number. The '+' isn't removed from the phone number in the IP-to-
Tel direction.
• You can also configure the Phone Context table using the ini file table
parameter PhoneContext (refer to ''Number Manipulation and Routing
Parameters'' on page 328).
