ESI Premise IP Server 900


ESI's IP 900 server is a 1U router style box that can have up to 196 VoiP phones plus digital/analog phones. Unlike many competitors, the ESI IP900 VoIP system has up to 8 expansion slots natively to add traditional equipment such as digital phones (max 64), Analog CO lines, Analog stations, and T1/PRI dialtone.

As with most VoIP based premise systems that interact with computers and smart phones, annual fees are strongly suggested to stay current with operating system and smart phone changes. Network up to 100 remote sites into one large system with Esi-Link. With proper licensing you can even bring your old brand x SIP phones. However, most find the feature benefits of a proprietary phone far outweigh the cost savings of bringing the old phones. However, to spread costs out over time it can be a stepping stone.

* 1U 19" wide Master Conrol Unit with 4 module capacity.
* T1/PRI module
* Digital 8 phone module
* Analog 4 station module
* Analog 4 line module
* 4 carrier module to allow modules 5-8
* 64 additional VoIP call capacity (base already has 63 channel capacity)
