sundance-communications.com/forum Forums TDM Business Telephone Systems Nortel Telephones & Systems DISA issue with VOIP trunks

Customer has an MPLS network with 1 BCM400 4.0(site A)and 2 BCM50's Rls 1(site's B & C). They can call from site to site with no problem over VOIP trunks. What they want to do is call from site's A & B locally to site C's area. They want toll bypass. I understand that the BCM does not support Auto/DISA DN over VOIP trunks. You can, however, use remote packages with VOIP trunks. At site C they are using routing to make their calls. Has anyone set this up before? If so I would appreciate any help on this.

Thanks

Sure, this can be done. You just have to manually manage the dialplans in each of the BCMs. You can identify all of the numbers that would be local to a particular BCM (area code + office code typically), then build a corresponding destination code in the remote BCMs. Point the destination code to a VoIP route for the appropriate site, strip the extra digits, and your call will complete. It can be a lot to manage if you have to touch very many systems. It's a great application for a Gatekeeper though...one dialplan to manage for the entire enterprise.

Good Luck!
