Create an Outbound Route Set the Dial Pattern to match any dialed number string

beginning with a “9” Put your IAX2 trunk in the Trunk Sequence list.

Note: A dial pattern of “9|.” will strip off the 9 and pass the rest of the digits to the trunk.

Create an Inbound Route Allow inbound calls from

any trunk to be routed to a specific destination.

By not specifying a DID Number or Caller ID Number, any inbound call will match.
