Best IP Phone System 2009
The MX250 is an IP PBX platform that integrates multimedia communications for businesses, large and small, into a single server compact system. All connections are made through standard interfaces. The MX250 integrates the functions of many applications into one Unified Communications platform without the requirement of several disparate adjunct servers. By integrating these functions into a single unit, Zultys delivers a cost effective, easy to provision, easy to use system that is also easily managed and expanded. ![]()
The MX250 combines the functions of an Internet gateway (switch and router) with classic PBX functionality: PSTN line interfaces, analog circuits, auto attendant, call routing, voice mail, and Automatic Call Distribution. It further adds support for video calls and multi-media files, such as text-to-speech announcements, automatic conversion of voice mail messages into WAV files, and MXIE, Zultys’ award-winning unified communications client application. The system uses SIP (Session Initiation Protocol) to communicate with IP devices on the LAN or across the WAN. This industry standard protocol permits the connection of desktop phones, conference phones, and other SIP endpoints from many manufacturers. Administrators use a single intuitive GUI on a PC to configure and monitor every aspect of the system.
With the MX250, workers are accessible on a central communication system from any location with an Internet connection. Direct connectivity among all users is easily achieved, regardless of their location within a building, campus, city, region, or country. Users of the system have full access to all system features when logging in at the office, from home, while traveling, or from a different site, while retaining their own personal user identity.
All users, regardless of their role within the organization, enjoy a high quality voice system with access to productivity tools designed to increase their ability to get more done in less time. The system offers powerful applications such as presence, instant messaging, unified messaging, call handling, screen pops, and detailed call logs. These tools can operate on a single system or among multiple MX systems of varying sizes for a centrally managed platform that painlessly scales to support large enterprises.
The MX250 connects to a standard Ethernet switch, along with the connection of computers and IP phones. The connection to the LAN is made through one or two 10/100Base-T Ethernet ports on the MX250 main board, thereby providing redundancy. Additional redundancy is available with dual hard discs in a RAID 1 configuration, and AC and DC power inputs.
The MX250 provides three module slots that support the connection to the PSTN, legacy PBXs, and analog telephony devices.
SIP and Open Standards From The Beginning
The MX250 was designed and built from its inception to be an open standards IP PBX platform. Most similar products were either originally designed with IP in their core with telephony services added on top, or they are traditional PBXs designed with telephony at their core with VoIP added in later development. Systems of these types typically use proprietary phones and have closed architectures. Conversely, the architecture of the MX250 has been optimized to combine voice and data technologies while using standard interfaces and phones.
