We are looking for a solution for small sites with 4 CO trunks, 2 to 4 analog stations, 5 to 20 46xx VoIP phones, all with BASIC local survivability. We use the G700/LSP a lot and have tried the Multitech. These would do the job but we'd consider a G150 or G250. Does anyone have any experience with these? Does the basic local survivability work for the 46xx phones or just the internal station ports?
