Hello. I want to propose for purchasing a VoIP gateway to connect some PRI lines with FS. Basic operation has to be routing like this: One line PRI will be connected to phone provider. Some calls to certain numbers thru this connection must be routed to FS via IP. Other destination numbers must be routed to second PRI connection for legacy PBX for analog phones. So the VoIP gateway must have two PRI (T1/E1) connections and two LAN connection for failover. After a while this VoIP gateway will be as a tehnology converter from IP to PRI. So LAN connectors will be used for connection to FS in a failover manner. And two PRI connectors will be used to connect to legacy PBX which have two PRI inputs to handle 60 concurrent connection. I've spotted three models: 1) Patton SN4951/4E60V2GS/EUI 4T1/E1/PRI 60 VoIP Channels G.SHDSL for $5,000 2) Audiocodes Mediant 1000 M1K-D2 2T1/E1 for $3,800 3) Sangoma Vega 400 2 T1/E1 Digital Gateway for $4,437 Which of this is a better working solution with failover and extended call routing plans?
