I don't have an answer for you, but I've got a customer with 6 remote offices in the bay area all of which have MICS 6.1, and all of which are using point to point t-1's for their data using Cisco 1900 series routers. How well does the VOIP Gateway work? Can you provide me with a source for reference materials? Ol' Nortel.com has limited my access....I'm needing to somehow resolve that. j8762
