One aspect first to understand is the advantages IP interfaces provide to a business telephone system. IP connections basically improve the flexibility of a business telephone system, particularly in managing extensions. It is much easier to move phones within the office. An IP interface also provides support for locating compatible phones in home offices and making connections when travelling. Also, systems with a built-in Session Initiation Protocol (SIP) feature allow connecting over the Internet without any further hardware for analog to digital conversion.
Some of the most popular commercially available systems today are Panasonic, Avaya Partner, Lucent, Merlin, Nortel Norstar, Comdial and Vodavi (from Vertical), NEC, Toshiba, Mitel, and Shoretel phone systems. Not all of these systems support IP features, so we suggest consulting your local provider for the latest available features. In addition to a "traditional" phone system, any PC or computer can be used as an IP phone system with downloadable free software. Keep in mind that "free" systems will require a significantly greater level of skill on your staff (or from your local provider).
