The majority of business telephony systems introduced over the past year have been designed for small or mid-sized businesses (SMBs) or branch offices of larger organizations that have fewer than 750 employees. A significant number of these SMB systems address very small businesses, those with under 100 employees. In addition, most of the new, small business telephony systems now come complete with pre-loaded business applications, eliminating the need for the separate software or hardware that is typical with traditional PBX systems. Top applications for SMBs are focused on business continuity with capabilities that facilitate collaboration and the ability to reach others quickly and efficiently. And, mobility options seem to be in the forefront. Just in the last few months, several manufacturers have introduced new mobile options, including Mitel, Samsung, Siemens, ShoreTel and Toshiba, to name a few. Siemens, for example, designed its HiPath OpenOffice for SMBs with a built-in controller for integrated voice over wireless LAN connectivity, and it includes one-number service and mobile twinning as standard features.
