Parameter  Description 
PhoneContext_Ton, PhoneContext_Context; 
[\PhoneContext] 
For example: 
PhoneContext 0 = 0,0,unknown.com 
PhoneContext 1 = 1,1,host.com 
PhoneContext 2 = 9,1,na.e164.host.com 
Notes: 
  This parameter can include up to 20 indices. 
  For a description of the table's parameters, refer to the 
individual parameter descriptions below. 
  Several entries with the same NPI-TON or Phone-
Context are allowed. In this scenario, a Tel-to-IP call 
uses the first match. 
  Phone-Context '+' is unique in that 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. 
  To configure the Phone Context table using the Web 
interface, refer to ''Mapping NPI/TON to Phone-Context'' 
on page 128. 
  For a description on using ini file table parameters, refer 
to ''Format of ini File Table Parameters'' on page 191.

to the called number for Tel-to-IP calls. 
  [0] No = port number/ not added as prefix (default). 
  [1] Yes = port number/ added as prefix. 
If enabled, the  port number (single digit in the range 1 to 8 
for 8-port devices, two digits in the range 01 to 24 for MP-
124) is added as a prefix to the called (destination) phone 
number. 
This option can be used to define various routing rules.
