If I understand well your request, under CUCM trunk configuration, you could use Prefix DN = 60 in the Inbound Calls section. Careful, as that would prefix all calls coming from the Avaya; eg. that could be an issue if you use this trunk to reach PSTN.

Otherwise, you could use translation-patterns and prefix only when the specific pattern is matched.

hi george,

i dit it, but still 4 digit come out.

any suggestion.

thanks

Please describe the exact call flow (devices/protocols involved), calling/called numbers and where exactly you applied the translation mechanism.

In my case the call flow is the following: Cisco phone > UCM > SIP TRunk > ITSP (there is not CUBE neither Gateway).

The output of the UCM is 7XXX and the ITSP needs the full number 1887XXX, so UCM has to add the prefix 188. I´m looking for it, but I haven´t found any solution yet.

Any idea about it?

Not sure if this is for calling or called number but if you have a route pattern for 7XXX, you can add prefix using the Called Party or Calling Party Transformation on the RP itself.
If your outgoing calls use a TP as well, both of those options are present there as well. You can also make the change on the route list or on the SIP trunk itself.
So effectively there are several places to accommodate this change. It depends upon which one you prefer to use.

Thanks Nipun, but the SIP Trunk only has the Prefix DN option for inbound calls.

If you go to the specific RP, the Prefix Digits (Outgoing Calls) option only changes the calling numbers.

Any another idea?

[R0g22]

On the SIP trunk would have a Called party transformation CSS which makes use of the called party transformation pattern to make changes. I never said that there is a prefix digit option specifically on the SIP trunk.

On the RP there should be a Calling Party Transformation and a Called Party Transformation. Both of them should have a Prefix Digits option.

Look up CUCM config and admin guides.

Good!...

It worked properly when I set the Called Party Transformation on RP.

Thank you very much!
