Routeadmin

Today I turned up a full PRI in Northern Virginia ( NoVA ). The carrier was Paetec. This was one of the first PRI's I have done in such a major metro area as DC/NoVA. Interestingly enough several things came out of this that might be worth mentioning.

The customers gateway was H.323 and they were running CUCM-BE 6. I configured the traditional Route Patterns, Route List, Route Group, and Gateway in CUCM-BE. The dial-peer's in the H.323 gateway proved to be quite problematic based on the carriers switch.

When I was placing an outbound international call, CUCM-BE was setting the ISDN Type to "International", I kept getting a telco message about the number being disconnected. I knew this wasn't the case since I have called this number ten thousand times. It's the Melbourne Australia Bureau of Metrology ( weather line ). The number from CUCM-BE was dialed as 9 011 613 9669 4603. Then I ran this across to one of my colleges. We had to play with setting the ISDN Type and Plan using a Translation Profile on the H.323 gateway. Below is a snippet of what we did to achieve this:

!
voice translation-rule 1
rule 1 // // type any unknown plan any unknown
!
!
voice translation-profile International
translate called 1
!
!
dial-peer voice 103 pots
translation-profile outgoing International
preference 1
destination-pattern 9011T
progress_ind setup enable 3
progress_ind connect enable 8
direct-inward-dial
port 0/1/0:23
prefix 011
!

What this did was effectively match any international call and mark the ISDN type and plan to "Unknown" which for whatever reason the telco switch wanted to see.

Hope that helps someone out one day.
