Excel Switching and Mediaring Enter VoIP Partnership

Excel Switching Corp. announced successful interoperability lab tests between its PSTN to IP gateway and MediaRing’s VoizBridge session controller. The joint solution enables carriers to expand their offerings of IP services such as VoIP wholesale (prepaid and postpaid), VoIP calling cards, enterprise VoIP and IP conferencing and fax. Both solutions seamlessly interoperate between H.323 and SIP, thereby protecting a carrier’s investment in legacy equipment while allowing the carrier to expand into the burgeoning VoIP market. http://www.xl.comhttp://www.mediaring.com
