The 1600/2400/3200 is a SIP-based analog voice gateway that provide voice/fax communication over the IP network (VoIP/FoIP). It links traditional telephony networks to IP networks with conventional telephony devices such as analog phones or fax machines.

The highly flexible call routing settings allow the administrator to configure different routes for calls based on the dialed number. Both proxy based calls and peer to peer calls are supported simultaneously. It supports phone book to place peer to peer calls without going through a VoIP server. By routing calls over the Internet or any IP network, this gateway can reduce or eliminate long distance or inter-office phone charges. Corporations can also enjoy the benefits of network consolidation and improved controllability of the telephone system.
