Top two Asterisk-based UC IP-PBX Appliance Manufacturers

Our criteria for selecting the two best on-premise Asterisk-based IP-PBX systems included factors like the initial price, as well as the total cost of ownership over time. We also expected an easy to use GUI incorporating built-in how-to help along with user-friendly intuitive configuration rules. An equally critical consideration was uncomplicated phone provisioning for users who prefer to install and manage the system themselves.

Our two top on-premise Asterisk-based UC IP-PBXs; Number one, the Grandstream UCM6302. Number two, Sangoma's PBXact appliances.

Our two leading choices each deliver an impressive array of built-in integrated Unified Communication features which allow remote users to connect securely and collaborate effectively. Additionally, both platforms support system expansion, within its limits, with the ability to turn on a feature without incurring any license fees.
Our focus, therefore, was primarily on UC components, reliability, ease of installation, cost, and the ability for self-management and administration. Plus, the ability to obtain support from the manufacturer.

The preferable choice is to select phones from the same manufacturer for ease of installation and consistent operation.

Each of the systems is capable of utilizing any SIP standard phone; however, electing to install the manufacturer's phones proved to remain the optimal choice, contributing to simple straightforward provisioning and smooth configuration. Plus, support from the manufacturer expanded significantly when their own phones were employed.

Lastly, too often an effective affordable system comes along from a PBX company only to be discontinued. With countless changes continuing within the telecom and communications industry, recognition of each manufacturer's resources and perseverance was considered.
