Does the MVP130 work on a dial up (low band) Internet connection?

The MVP130 will work on a dial up connnection. You can set the codec so that it uses bandwidth between 5.6K to 64K per channel. In this case, you want to use a codec with the least bandwidth. The MVP130 can be configured for FXS or FXO interface. It supports H.323, SIP, and SPP (Single Port Protocol). I don't recommend our other gateways on a dial up connection. Do not try more than one call on dial up.
