XOP Network announces that San Isabel Telecom is using the XOP Networks' Universal Service Node with simultaneous T1 and SIP connectivity to provide voice mail to both traditional and VoIP customers. San Isabel Telecom is a facilities-based provider of voice and data services in several mountain regions of Colorado. The company was started by Doug Wagner in 1996 to meet the communications needs of the ever-growing Vail Valley. San Isabel also serves the Aspen and Basalt areas.

San Isabel Telecom has a TDM network with a Alcatel-Lucent 5ESS switch, and a next generation packet based VoIP network with a Cisco Gateway and Acme Packet Session Border Controller. San Isabel is meeting the challenge of providing voice mail to customers on the TDM network and the VoIP network at the same time by using the XOP Networks' USN to connect to the 5ESS switch and the VoIP based SBC equipment.

In addition to providing TDM and SIP connectivity, the USN based Voice Mail application allows voice mails to be accessed by telephone, web portal and PDAs such as iPhone and Blackberry. The PDA access is unique in that voice mails can be accessed in random order simply by a click on the PDA based web portal.
