The SmartLink™ 4250 is a full function IP-PBX designed to meet the needs of medium to large enterprises. It provides the features of a traditional PBX with the benefits of VoIP such as soft clients and voicemail to e-mail integration. The SL4250 is available in 75 to 1,000 user license versions, coming with common PBX/Key System features such as an auto-attendant, configurable call routing, music on hold, call-forwarding, music on park, hunt groups, and much more.

The web-based administrative interface permits quick and easy configuration of dialing plans, auto attendants and other PBX features. Office users of the SL4250 IP-PBX benefit the most from the voicemail to e-mail integration. An easy to use web page is available to create and manage personal voicemail folders. Menu options facilitate the setup of e-mail notification and even email delivery of the message in easy to open .wav file format. Multiple greetings can be recorded and then activated via a drop drown box.

Enterprises operating in multiple locations can leverage their existing data intranet/VPN investment to simplify extension dialing. Every employee can be reached via a 3-digit extension by a simple web page configuration of the dialing plan. Intra-enterprise long-distance phones bills drop to zero by using the VPN. At the same time, additional savings can be achieved both by reducing the number of local PSTN connections, as well as by leveraging the remaining local PSTN connections in remote offices to effect a least cost routing of long distance calls to the remote office area code and thereby performing a long distance toll by-pass.

When combined with a Patton SmartNode or SmartLink device, the SL4250 IP-PBX provides VoIP services to analog phones, faxes, and legacy PBX systems that are not able to support newer VoIP technologies.
