Mapping Npi/Ton To Phone-Context - 3Com VCX v7111 User Manual

Dialing Plan Notation
The dialing plan notation applies, in addition to the four Manipulation tables, also to Tel IP
Routing table and to IP Hunt Group Routing table.
When entering a number in the destination and source Prefix columns, you can create an
entry that represents multiple numbers using the following notation:
[n-m] represents a range of numbers
[n,m] represents multiple numbers. Note that this notation only supports single digit
numbers.
x represents any single digit
# (that terminates the number) represents the end of a number
A single asterisk (*) represents any number
For example:
[5551200-5551300]# represents all numbers from 5551200 to 5551300
[2,3,4]xxx# represents four-digit numbers that start with 2, 3 or 4
54324 represents any number that starts with 54324
54324xx# represents a 7 digit number that starts with 54324
123[100-200]# represents all numbers from 123100 to 123200.
The VoIP gateway matches the rules starting at the top of the table. For this reason, enter
more specific rules above more generic rules. For example, if you enter 551 in entry 1 and
55 in entry 2, the VoIP gateway applies rule 1 to numbers that starts with 551 and applies
rule 2 to numbers that start with 550, 552, 553, 554, 555, 556, 557, 558 and 559. However if
you enter 55 in entry 1 and 551 in entry 2, the VoIP gateway applies rule 1 to all numbers
that start with 55 including numbers that start with 551.

Mapping NPI/TON to Phone-Context

The Phone-Context table is used to configure the mapping of NPI and TON to the Phone-
Context SIP parameter. When a call is received from the ISDN, 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).
You can also configure the Phone Context table using the ini file parameter PhoneContext
(see Protocol Management ini File
