Our criteria for our two best on-premise IP-PBX systems included factors such as the initial expense, as well as the total cost of ownership, built-in and user friendly features, reliability, ease of installation, management and administration. Two additional considerations were the ability to expand the system without any license fees and available support from on line communities and the manufacturer so that companies with IT personnel can manage the voice side of the LAN, as well as the rest of the network.
The ability to use many of the available SIP phones on the market and not be married to any particular phone was another important condition. Although the first choice with a new installation is to pick phones from the same manufacturer for ease of installation, a more reliable feature set without hiccups, as well as better and easier support from the manufacturer, however many companies want the ability to use Polycom, Yealink, or other popular SIP phones.
Lastly, too many times a good affordable system comes along from a PBX company only to be discontinued, either from financial problems causing bankruptcy, reorganization, or a competitor's take-over and then a decision to discontinue of the product, perhaps because it competes too well with their other products.
Both manufacturers of our two choices have proven to have staying power, strong businesses with a line of proven products and both offer a line of appliances from small to large and build their own SIP compliant IP telephones.
