RE: Problem with VoIP Dial Peers / Destination Patterns (Case B533406 - FXO {FOREIGN EXCHANGE OFFICE} - configuration issues)

- Neat trick with the TAC case link. . .

- If anyone has any additional ideas, I am
  open to them. . .

- Based on a private reply to the problem
  that mentioned using a $ character as the
  null at the end of both voice peer 9 and 91
  destination patterns.

  Liked the idea, appealed to the logical. . .

  Cured the show dialplan number issue quite
  well, but didn't resolve the issue of this
  working with real lines.

  IOS's tried: 12.1.5T7 and 12.1.3XA

  Have tried to invoke the power of a router
  reload. . .

- Someone also mentioned that under the 911
  peer that prefix 911 should be there.

  In testing with 411, we found that it is
  not needed. Is a prefix needed? Opinions?

- Current applicable configuration, and in
  this order, I have tried reordering them
  for grins:

  I have dumped the 9T for now. . .

  !
  dial-peer voice 911 pots
   destination-pattern +911
   port 1/1/0
  !
  dial-peer voice 91 pots
   destination-pattern 91..........$
   prefix 1
   port 1/1/1
  !
  dial-peer voice 9 pots
   destination-pattern 9.......$
   port 1/1/1
  !

Sounds to me like you need to play around with adding a $ to the end of
the dial strings -- my abbreviated understanding of VoIP is that the $
will compare all dialed digits, so you don't confuse things by having two
dial strings that being with 9. It's pretty well documented in the 12.2
docs on CCO under dialing patterns & strings.
