¾ To configure the Phone-Context tables, take these 4 steps:
1. Open the 'Phone Context Table' page (Configuration tab > Protocol Configuration
menu > Manipulation Tables submenu > Phone Context Table page item).
Figure 3-76: Phone Context Table Page
2. Configure the Phone Context table according to the table below.
3. Click the Submit button to save your changes.
4. To save the changes to flash memory, refer to ''Saving Configuration'' on page 265.
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 364).
