Allworx is heavily vesting the small business VOIP market and offers several phone systems and accessories. The Allworx 6x VOIP PBX combines full PBX and VOIP duties with networking functions, including automated backup, Web server, e-mail, security and LAN management. Allworx offers all of the critical PBX capabilities and matches Critical Links and Sutus as far as VMX, routing and other VOIP options go.

Allworx 6x is ideally placed at the edge of a small network and functions as a firewall and router for connecting phones and PCs to the Internet. The unit features four analog connectors, which incorporates POTS into the PBX. The combination of POTS support with VOIP features allows the device to be installed over time. In other words, customers do not have to re-engineer their phone systems and network connectivity overnight, allowing for a gradual VOIP transition.

Allworx 6 has an initiative installation wizard, browser-based management console and other support tools. However, the company recommends installation by its solution provider partners; it’s sage advice, since the unit is anything but plug and play. Installers will need to have a good understanding of networking, firewalls and routing.

With a device as complex as the Allworx 6x, management features are critical. Administrators will find it a breeze to set up voice mail boxes, call routing and the dozens of other features available on a PBX. The same ease of management applies to the unit's networking features. VPN connections are straightforward to set up, as well as remote access.

The device provides a platform for setting up unified messaging, thanks to integrated e-mail support, as well as group scheduling and customizable Web portals for each user. The Allworx 6x includes an eight-seat conference bridge, which eliminates the need for businesses to rely on external conference services.

Pricing is very competitive; users can get set up with an eight-user Allworx 6x system (eight phones included) for under $3,000. For solution providers looking to offer an advanced but affordable VOIP PBX that integrates well into small networks, the Allwork 6x is a good choice.
