Veraz Networks has expanded its line of media gateways for bridging the gap between TDM and IP networks. 
The new I‑Gate 4000 EDGE SIP Gateway (GW) enables Service Providers to offer SIP trunking services that their business customers can use to interconnect existing PBXs to remote offices, teleworkers, and local and long-distance PSTN services. The gateway can be scaled from single PBX sites to multi-tenant buildings and industrial parks with multiple customers' PBXs. In addition, the I-Gate 4000 EDGE SIP GW provides Veraz's high voice compression to deliver toll quality at significantly reduced bandwidth.
The I-Gate 4000's key differentiators include:
- Six 9's reliability
- 30 to 50% reduction in size for the same maximum traffic load. The I-Gate 4000 EDGE SIP Gateway provides sustained high call-handling performance independent of traffic load.
- Easy to use and comprehensive digital handling and call routing features.
- Demonstrated multi-vendor interoperability.
The I‑Gate 4000 EDGE SIP GW is available directly from Veraz and through select partners.
