The MultiVOIP® SS survivable SIP gateway and server is ideal for small branch offices of large corporations that have deployed a distributed IP telephony network. It functions as the primary or secondary SIP server for IP phones used at the remote offices and renders local office survivability, in the case of a LAN or WAN failure, by providing local, reliable PSTN trunking. The MultiVOIP SS gateway also provides local PSTN access for emergency calls, such as 911, as well as normal inbound/outbound local calling. In addition, the gateway functions as an analog telephone adapter (ATA), adapting analog phones and fax machines to IP environments.
