ini File Field Name
Web Parameter Name
Valid Range and Description
PhoneContext
Defines the Phone Context table.
Format for this
ini
file parameter table:
[PhoneContext]
FORMAT PhoneContext_
Index
= PhoneContext_
Npi
,
PhoneContext_
Ton
, PhoneContext_
Context
;
[\PhoneContext]
Where,
ƒ
Npi = Number Plan
ƒ
Ton = Number Type
ƒ
Context = Phone-Context value
When a call is received from the 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:
ƒ
For an explanation on
ini
file parameter tables, refer to 'Structure of
ini File Parameter Tables' on page 253 .
ƒ
This parameter can appear up to 20 times.
ƒ
Several entries with the same NPI-TON or Phone-Context are
allowed. In this scenario, a Tel-to-IP call uses the first match.
ƒ
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.
ƒ
To configure Phone Context table using the Embedded Web Server,
refer to 'Mapping NPI/TON to Phone-Context' on page
