Description:

The MX25 is a modular device that is capable of operating in two different modes. In one mode of operation, the MX25 is a stand alone SIP to PSTN gateway. When operating in this mode, the MX25 converts the format of a phone call to allow it to pass between the IP network and the public telephone network. The MX25 is also capable of operating as a system that extends the functions of the MX250 to a branch office with 25 or fewer users. In this configuration, the MX25 communicates with the MX250 and exchanges information regarding users and devices. Even when there is a failure in the WAN link connecting the MX250 and the MX25, the MX25 continues to operate and allows for incoming and outgoing calls to the PSTN.
