International Dialing Pattern

[Tranman79]

Having an issue at a client's phone system - apparently they've been able to dial internationally no problem up until around a couple of months ago.  Their IOS configuration hasn't been changed from what I can tell and in talking with Spectrum Business voice it looks like our 4321 ISR isn't forwarding the international digits.  As soon as I dial 8011 it says it's unable to dial.  Any ideas here?  I've attached a "clean" config.

Yes exactly.  Just stops cold at that point.

Right.  This is CME, with the configuration given in your first post?   If that's the case it should be waiting until 3 seconds after you've dialled the last digit before trying to place the call.  Your international dial peer has destination pattern of 8011T so will match anything starting 8011 but the T means any number of additional digits.

Can you check that the you still have the interdigit timeout set to a sensible value ..

voice register global
 mode cme
 source-address 10.1.4.2 port 5060
 timeouts interdigit 3

This is very symptomatic if an overlapping dial plan and the culprit here is your dial peer voice 9 config..

dial-peer voice 9 pots
description OUTBOUND 8.11 Digit Dialing
 translation-profile incoming OUT
 translation-profile outgoing OUT
 destination-pattern 8.11
 port 0/2/0:23

 This is matched over your dialpeer voice 8 which allows for more digits to be collected. Please do a shut on dialpeer 9

shut

Test again

Looks like shutting down dial-peer voice 9 worked!  Now a couple of additional questions (since I'm new to Cisco IOS)

1. Should I just remove dial-peer voice 9 pots from the configuration completely?
2. Why would there have been the two different dial-peers in the system to address international dialing in the first place?

I am not sure why dial-peer 9 exist but if its for international dialling then its improperly configured. You can safely remove it. It is doing nothing other than creating trouble for you..
