Multi-Tech Systems and Xten Collaborate on SIP

Multi-Tech and Xten Demonstrate Interoperability between MultiVOIP Voice over IP Gateways and Xten SIP Softphones

Multi-Tech Systems and Xten Collaborate on SIP

Vancouver, BC, Canada — September 05, 2014

Multi-Tech and Xten together have achieved SIP interoperability between MultiVOIP Voice over IP gateways and Xten’s family of SIP softphones. Xten provides a cost-effective, high-quality “software-only” IP phone that can talk to any MultiVOIP gateway. Together, the solution provides Voice over IP mobility allowing road warriors to capitalize on toll bypass voice connectivity.

“If you want to make calls via the Internet, and you are mobile, the best way to do that is with one of our softphones on your laptop,” explains Erik Lagerway, President and Chief Operating Officer of Xten. “With Xten softphones and Multi-Tech MultiVOIP Gateways, deploying SIP-based VoIP networks for SMEs and SOHO businesses is a no-brainer.”

Attaching MultiVOIP to an IP-based PBX creates an interconnect to the PSTN that allows mobile users to use the Xten Softphone to make toll-free telephone calls from anywhere in the world into their corporate office, or use their IP PBX to make calls out of their local exchange. Conversely, callers can come from a local exchange into the PBX and out to the Xten software via the MultiVOIP gateway.

“SIP is gaining a lot of momentum in the industry,” explains Chip Harleman, Vice President of Sales and Marketing for Multi-Tech Systems. “Our alliance with Xten opens the door for SIP-based, mobile, Voice over IP applications. In fact, we advocate multi-vendor SIP implementations. We believe that interoperability benefits the entire industry and ultimately our mutual customers.”

The MultiVOIP family is available in analog and digital models ranging from one to 60 ports. MultiVOIP gateways connect directly to phones, fax machines, key systems, PSTN lines or a PBX to provide real-time, toll-quality voice connections to any office on a VOIP network. It is designed to help maximize investments already made in the existing data and voice network infrastructure and is SIP (RFC 3261) compliant.

Xten’s X-PRO softphones are business-grade IP Telephony solutions, delivering the quality of service and features found in business-class telephones including conferencing and multi-proxy. Xten also has a feature-rich FREE softphone dubbed X-Lite which does not include some of X-PRO’s premimum features but still provides the same level of call quality. Xten’s softphones are fully RFC3261 (SIP), RTP/RTCP (RFC 1889) and SDP (RFC 3264) compliant. They are available for Windows (Windows 98SE/ME/NT 4/2000/XP/CE), macOS and LindowsOS operating systems.
