[cisco-voip] How to globalize national calls based on calling device pool?

[Zoltan.Kelemen at Emerson.com]

There is a large CUCM installation, with sites in various European
countries. Devices from different sites are in different Device Pools and extensive use is
made of the Local Route Groups.

Now there is a connection to a new provider over a SIP Trunk and a CUBE. However all calls
made to this provider are expected to be sent in +E.164 format (globalized). There would
be also benefit in sending various national calls as well to this provider.

Current Route Pattern for national calls is:
0.0! towards Local Route Group
with H.323 gateways dropping the leading 0 and sending the call out to PSTN.

How can the dialed numbers (ex. 001234567) be globalized according to the originating
Device's Device pool?

I.e. if a phone from Germany dials the number above, +4901234567 should be sent to the SIP
trunk, but if a phone from the UK dials the same digits, +4401234567 should be sent to the
SIP Trunk.

The translations could be done either on the CUCM cluster or on the CUBE, however, cluster
based solutions would be preferred.

There is also a larger number of sites/countries involved, so some scalable solution would
be best.

Outbound callerIDs are correctly set.

Any ideas would be appreciated :)
