IP PBXs Come Into Their Own


Sales of enterprise IP telephony systems increased more than 25 percent year over year in 2005, according to Synergy Research Group. By comparison, the sale of conventional PBX systems decreased 33 percent. Of the $2.88 billion U.S. businesses shelled out for both TDM and IP-based telephony systems last year, IP voice systems garnered more than half; 62 percent to be exact, according to Synergy. This jibes with our recent IP PBX reader poll, in which 59 percent of respondents said they have an IP PBX in production or will within 12 months. These figures reflect the growing maturity of IP PBXs. As recently as the late 1990s, IP telephony systems were characterized by limited sets of calling features, doubtful reliability, restricted scalability, and haphazard voice quality and security. Today, however, new levels of reliability, sophistication and functionality have IP PBXs poised to completely--albeit gradually--replace their legacy forebears. We see migration to an IP telephony platform as only a matter of time for all enterprises, regardless of size or industry segment.
