Emeryville, CA

SysMaster Corporation, a leading provider of Voice-over-IP and networking solutions for the enterprise, announced today that its VoIP Gateway now supports both H.323 and SIP protocols. The dual SIP/H323 support makes SysMaster VoIP Gateway a truly universal element in any VoIP infrastructure.

“SIP has established itself as a preferred signaling protocol for new VoIP applications due to its simplicity and ease of programming. While we don’t know whether SIP, H.323 or some other protocol will dominate the VoIP market in the future, we consider adding SIP support to our gateway critical as we move towards becoming a one stop shop for telecom providers,” said Michael Fahey, SysMaster Director of Sales. “Looking forward, we will continue developing VoIP equipment that supports broad range of standards and that is compatible with VoIP equipment produced by other leading manufacturers”.

SysMaster VoIP Gateway is a carrier-grade, SIP/H.323 compliant gateway that supports up to 120 PSTN channels through E1/T1/ISDN/PRI lines or up to 240 single VoIP channels. The gateway routes all incoming calls via PSTN or VoIP channels based on custom routes for individual resellers and/or users. It supports SIP, H.323 v2, v3, and v4 protocols, G729A/B/AB, G723.1, G726, and GSM codecs capable of operating concurrently, proxy services, and multiple gatekeeper registrations. With an optional add-on module, SysMaster VoIP Gateway can operate as a callback gateway and initiate callback services via one of the following methods - Web, Email, SMS, or ANI.

The Session Initiation Protocol (SIP) is an end-to-end, client-server session signaling protocol for Internet telephony, conferencing, presence, events notification and instant messaging. Although not limited to internet telephony, with its textual coding, globally reachable user address and ease of programming, SIP is steadily gaining market share. Companies developing media servers, gateways, soft-phones, PBX, IP phones and other VoIP devices increasingly rely on SIP.
