AddPhoneContextAsPrefix

a prefix to the outgoing ISDN SETUP Called and Calling numbers.

PhoneContext
[Phone Context Table]
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).
PhoneContext = <Number Plan>,<Number Type>,<Phone-Context>
For example:
 PhoneContext = 0,0,unknown.com
 PhoneContext = 1,1,host.com
 PhoneContext = 9,1,na.e164.host.com
Note 1: This parameter can appear up to 20 times.
Note 2: Several rows with the same NPI-TON or Phone-Context are allowed. In
this scenario, a Tel-to-IP call uses the first match.
Note 3: Phone-Context '+' is a unique case 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.
