SIP User's Manual

This parameter table can include up to 20 indices (1-20).

The manipulation rules are done in the following order:
RemoveFromLeft, RemoveFromRight, LeaveFromRight,
Prefix2Add, and then Suffix2Add.

If the table's matching characteristics rule (i.e.,
DestinationPrefix, RedirectPrefix, SrcTrunkGroupID, and
SrcIPGroupID) is located for the Tel-to-IP call, then the
redirect number manipulation rule (defined by the other
parameters) is applied to the call.

Redirect number manipulation for Tel-to-IP calls is not
performed if the CopyDest2RedirectNumber parameter is
enabled. This parameter copies the received destination
number to the outgoing redirect number.

The parameters NumberType and NumberPlan are
applicable only to the SIP Resource-Priority header.
This parameter table 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, the NPI
and TON are compared against the table and the
corresponding 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 (Request-URI, To, From, Diversion) where a phone
number is used.
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.

Several entries with the same NPI-TON or Phone-Context
are allowed. In this scenario, a Tel-to-IP call uses the first
match.

To configure the Phone Context table using the Web
interface, see 'Mapping NPI/TON to SIP Phone-Context'
on page 291.

For a description on using ini file table parameters, see
'Configuring ini File Table Parameters' on page 88.
Determines whether the received Phone-Context parameter
is added as a prefix to the outgoing ISDN Setup message
withCalled and Calling numbers.

[0] Disable = Disable (default).

[1] Enable = Enable.
