Al, you're always in the mix if we ever do anything major..

But for now My location currently has an s8700 CM3.1 with MM and I have 4 other domestic sites with s8300's that are all connected to an MPLS network where we use IP trunking between offices and they all share the NY MM but are not LSP's. Also another location in LDN that has it's own s8700's.. MM that controls other Intl offices.

We have now aquired another company who has an office in NY with an s8500, intuity audix and they have some domestic sites (houston, LA, ldn that have s8300's and IA770's) that are not lsp'd and they do 4 digit dialing across vpn.

So we are taking over these switches and there are some small overlaps in teh dialplans where there are exact same DID's. Any suggestions on a day 1 scenario that will have no impact to the users and then what things should look like infrastructure wise going forward? we want to do 4 digit dialing between these new offices and be able to network vm.

My thoughts were.. day 1 do nothing!!
or have the overlapped users change their numbers and then assign a prefix per location. but there may be some resistance to changing numbers for some.

going forward I'm thinking we will be looking at either an ESS or lsp'ing these other locations and 6 digit dialing??
