--Image: Internet Telephony 2007 Product of the Year -- The Smart-DTA enables integration of ISDN network users into a local VoIP phone service, or extends an ISDN line of a PBX to a remote site over IP. It offers a simple end-user configuration interface and connects both to a PBX in point-to-point mode and an So bus in point-multipoint mode.

Unlike most other products on the market, Patton’s intelligent call routing technology does not only offer simple ISDN to VoIP, but also advanced features like number plan adaptations, mappings between ISDN and SIP/H.323, manipulation of call properties through regular expressions, routing calls based on time-of-day or bearer capability criteria and much more.

Providing power to the ISDN line, the S-DTA eliminates the need for an external power supply to provide power to the terminals. Gateway functions use standard CODECs such as G.723, G.729, and T.38 fax as well as industry standard SIP and H.323 signaling protocols to ensure seamless connection and compatibility for all voice services. Quality of service (QoS) features complete the offering with advanced voice prioritization and traffic management including VLAN tagging, 802.1P/Q and DSCP.

Network Integration
