I-Gate® 4000 SIP Gateway
 

The I-Gate 4000 SIP Gateway enables service providers to reduce the cost of supplying voice services to enterprise customers using legacy TDM PBXs by allowing them to access IP and SIP-based services. In addition, multi-site enterprises can use the I-Gate 4000 SIP Gateway to interconnect locations that are still using legacy TDM voice switches with other sites that have already been migrated to VoIP.

The I-Gate 4000 SIP Gateway can be deployed in a fully redundant configuration providing six-nines reliability and high availability. Its support for full system redundancy is without comparison, and lack of full redundancy means typically having to settle for availability below five-nines. High reliability is especially important because the I-Gate 4000 SIP Gateway is often placed at the customer premise, where access may be difficult and time-consuming.
