Leave the top fields blank

18. Simple IAX2 Trunking Put the Peer PBX IP address on the PEER Details
Configure both PEER and USER type=friend
There is no registration or password required between PBXs, so do not implement this on a real system unless you are sure of what you are doing.

19. 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.

20. 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.

21. Set the Inbound Route Destination
Direct the inbound route to a specific extension, ring group, IVR, etc.

Allow anonymous inbound SIP Calls makes testing easy, but can be a security risk.
