You can configure multiple rows with the same NPI/TON or same SIP 'phone-
context'. In such a configuration, a Tel-to-IP call uses the first matching rule in the
table.
•
To add the incoming SIP 'phone-context' parameter as a prefix to the outgoing
ISDN Setup message (for digital interfaces) with called and calling numbers, from
the 'Add Phone Context As Prefix' drop-down list (AddPhoneContextAsPrefix),
select Enable.
