[cisco-voip] Urgent Priority on Translation Patterns

[William Roy]

I have thought about a dummy gateway but was not sure how to implement. What I am trying to achieve is that we are moving a customer from a 4 digit dial plan to a 5 digit dial plan. The new system is CUCM 6.1 install with all of the IP phone now using  5 digits and we are integrated with an NEC PBX with an MGCP ISR gateways, the phones on the NEC are still using 4 digit. On the IP phones we want to be able to dial either the old 4 digit or the new 5 digit number. What I had setup was a 4 digit translation that added the 5 digit, then if it matched an IP phone it rang the IP phone, if it did not match an IP phone extension it sent it on a route pattern to the MGCP gateway and stripped off the 5 digit. That part worked for 4 digits dialing however it broke dialing a 5 digit extension of an IP phone, as some of the leading digits matched both the translation pattern plus the first digit in the 5 digit extension. So what I have currently setup is removed the translation, put in a  4 digit route pattern which points at the MGCP gateway, the call setup gets routed over the NEC and then routed back  to the CUCM cluster if the call is for an IP phone, CUCM translates the number to a 5 digit number inbound from the gateway. The downside of this is that we use up two channels on the E1 per call between IP phones when dialled using 4 digits. Hope the above makes sense.

 So I suppose if possible I need to setup the following...

4 digit route pattern to a dummy gateway,
Called number gets translated to a 5 digit pattern.
Call gets sent back to the CUCM, if the extension matches an IP phone extension - ring phone
If the 5 digit number is not an extension on the CUCM - match a 5 digit route pattern send call to the MGCP gateway connected to the NEC and strip of 5th digit.

Cheers

Translation patterns are always urgent.
You could possibly use a Route Pattern instead? dummy gateway maybe?

Really depends exactly what you are trying to do

Cheers,

Tim

Is there anyway that Urgent priority can be turned off on a translation pattern in CUCM 6.x? The doco suggests that it cannot be.
