Majority of the organizations have an existing investment made in their ISDN infrastructure. While low-tariff IP telephony has emerged as a viable alternative for long-distance calling with the IP infrastructure wide-existent. It is therefore necessary for the businesses using ISDN PBXs to provide VoIP connectivity to their users. This allows the users to dynamically select one of the networks on per-call basis for obvious benefits of cost and quality of service (QoS). Also, reaching a network transparently helps eliminating the huge interconnection charges and thereby saves significantly on call costs.
The VoIP-T1/E1/PRI gateway that offers integrated interfaces for VoIP and PRI/ T1/E1 networks. The gateway can be scaled up to as many as 8 T1/E1/PRI ports. The high-density VoIP card provides up to 32 simultaneous VoIP channels per card. With Universal Slot Architecture, the VoIP card can be scaled in equivalence to the maximum number of slots available with the ETERNTIY variant. The count of simultaneous VoIP calls increases by a multiple of 32, per VoIP card added. These modular gateways come in varied configurations, with built-in support for multi-port Auto Attendant, in-depth Call Records, DDI and Least Cost Routing.
