We are adding 20 more DID #s thru the PRI circuit to an offsite office which will not have an BCM just nortel phones. I was told this is called VOIP that will allow this to happen with out having an 2nd BCM.First, how do you set up the DN's and target lines for the new numbers to work functionally offsite or will someone really waste our time and money. I'm not sure this will really work with out an 2nd BCm; but I dont really know about VOIP. Please some understanding about what is needed to have this to work without an 2nd BCM. Thanks always
