Have an questions about using a gatekeeper for routing between dial plans on the same CUCM cluster.
I have come across an issue where the dial plan is very poor and as such we have overlapping dial plans. I have a couple of questions. Can a gatekeeper be used for intracluster routing, my understanding of the gatekeeper is that it routes intercluster dial plans and therr should only be one CUCM cluster per zone.
For example I have extension 1000 at site A and extension 1000 at site B (Can I just add this is not my design, I would not have done it this way)both on the same CallManager cluster. There is a site A partition for the A Phone and a B partition for the B phone. So if Site B ext 1000 calls site A 1000 then they would in turn add a prefix (say 554), this prefix then gets stripped off on the site A side and rings 1000, the call details then show 5551000 as the recieved call so when A calls B back it dials 5551000.
Is theis best to do this using a gatekeeper or using callmanager in a multitennant fashion. If I use the latter what effect will this have on Unity I would need to make this multitennant support also.
At the moment 1 site (the main and CUCM location)has 4 digit dial plan the other three much smaller sites have a 7 digit dial plan. (The idea is to have all sites 4 digits with intersite prefix)but want to see if I can do this on a gatekeeper or would it be best on the CUCM
If I had the chance to rediesign I would but its live and trying to tidy it up.
cheers once again
