Connecting to the local ISDN Phone as well as the local PSTN port, Patton’s SessionRouter™ technology links any standard ISDN telephone or PBX to VoIP while still connecting to legacy PSTN services. Built-in Lifeline support ensures phone connection to the PSTN in the event of failure.

Quality of Service (QoS) features complete the offering with advanced voice prioritization and traffic management.
