Positron G-640 E1/T1 PRI Office Gateway

The G-640 E1/T1 PRI Office Gateway is a powerful networking solution that will allow seamless communication for Enterprises in their migration to VoIP networks by providing integrated E1/T1 PRI interfaces that can be directly connected to a PBX for transparent encapsulation of voice calls into VoIP packets.

Not only does the G-640 E1/T1 PRI Office Gateway transparently provide the gateway functionality between the legacy voice and VoIP interfaces it can also perform advanced, automatic routing of calls, high performance voice compression for network optimization and can even automatically failover to the integrated GSM interfaces for network failure or least cost routing rules.

Features and Benefits

• Seamless Voice Routing - Quickly build a powerful routing & rules table that will direct voice calls to lower cost networks automatically
• VoIP Migration without the need to Change your Voice PBX - The G-640 Office Gateway will transparently connect to your existing network interface and efficiently convert all voice traffic to a high priority VOIP traffic link that is 100% transparent to your existing legacy PBX
• Automatic Failover between Voice Networks - Automatic trunk failure detection and route failover definition between PRI / GSM / Ethernet / 3G / FXO interfaces
• High Scalability - Four E1/T1 PRI, 10/100/1000 Mbps Ethernet and Voice Transcoding of G.729, G.711, G,722.1c and AMR codecs to 120 simultaneous channels make this a super scalable solution
