D24S Voice Gateway
Connect More. Replace Less.
With a simple and economical way to help legacy telephones, fax machines, and PBXs interconnect with an IP network, Bittel’s 24 ports analog FXS gateway enables call center and multi-branch enterprises to process powerful, versatile, and efficient VoIP solutions with unparalleled cost advantages. Connected between a PBX, LAN, or WAN, the 24 ports FXS VoIP Gateway converts analog PSTN messages into a format suitable for transmission over standard IP networks.
Designed for voicemail and unified messaging applications, the 24 Ports Analog VoIP Gateway D24S has a 10/100/1000M (optional) Base-T Ethernet connection for connecting legacy PBX to a LAN. The analog loop start functionality supports integration via in-band signaling (DTMF or FSK), serial protocols, as well as T.38 for fax transmissions over IP (FoIP).
