Defines the Phone Context table.
Format for this ini file parameter table:
[PhoneContext]
FORMAT PhoneContext_Index = PhoneContext_Npi,
PhoneContext_Ton, PhoneContext_Context;
[\PhoneContext]
Where,
Npi = Number Plan
Ton = Number Type
Context = Phone-Context value
When a call is received from the ISDN/Tel, the NPI and TON are
compared against the table, and the Phone-Context value is used in the
outgoing SIP INVITE message. The same mapping occurs when an
INVITE with a Phone-Context attribute is received. The Phone-Context
parameter appears in the standard SIP headers where a phone number
is used (Request-URI, To, From, Diversion).
For example:
[PhoneContext]
PhoneContext 0 = 0,0,unknown.com
PhoneContext 1 = 1,1,host.com
PhoneContext 2 = 9,1,na.e164.host.com
[\PhoneContext]
Notes:
For an explanation on ini file parameter tables, refer to 'Structure of
ini File Parameter Tables' on page 295.
This parameter can appear up to 20 times.
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 a unique 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.
To configure Phone Context table using the Embedded Web Server,
refer to 'Mapping NPI/TON to Phone-Context' on page 130.
