[PhoneContext]
SIP User's Manual
Description
[2] Copy before phone number manipulation = Copies
the called number before manipulation. The device first
copies the original called number to the SIP Diversion
header, and then performs Tel-to-IP destination phone
number manipulation. Therefore, this allows you to have
different numbers for the called (i.e., SIP To header)
and redirected (i.e., SIP Diversion header) numbers.
Notes:
For digital interfaces: If the incoming ISDN-to-IP call
includes a Redirect Number, this number is overridden
by the new called number if this parameter is set to [1]
or [2].
This parameter can also be configured for IP Profiles
(using the parameter IPProfile).
Determines whether the received Phone-Context
parameter is added as a prefix to the outgoing ISDN
SETUP message with (for digital interfaces) Called and
Calling numbers.
[0] Disable = Disable (default).
[1] Enable = Enable.
This ini file table parameter defines the Phone Context
table. This parameter maps NPI and TON to the SIP
Phone-Context parameter. 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)
The format for this parameter is as follows:
[PhoneContext]
FORMAT PhoneContext_Index = PhoneContext_Npi,
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
