Introduction
The SIP phone-context parameter qualifies a DN beyond the usual
Numbering Plan Identifier (NPI) and Type of Number (TON). In addition to
the NPI/TON, the phone-context parameter includes unique identification of
the scope for which the number is valid.
Example
If a CDP number is dialed within the Site1 CDP domain of the
COMPANYABC network and the call must be routed at the network level (by
a network router such as a CS 1000 Redirect Server or MCS 5100 Proxy
Server), then the number must be qualified with a phone-context parameter
that incorporates the following:
•
NPI = Private
•
TON = CDP
•
Enterprise ID = companyabc.com
•
CDP Domain ID = Site1
These elements must be combined such that the resulting string is globally
unique.
