Choosing a VoIP vendor: A buyer's guide
A collection of articles that takes you from defining technology needs to purchasing options
Editor's note: This article is part of a series on voice over IP (VoIP). The feature articles in this series describe the evolution of VoIP, its use cases, and the important criteria to consider when buying a VoIP service. The series also compares the top VoIP products in the marketplace. This article gives an overview of Adtran VoIP products.
The NetVanta series is the main Adtran VoIP offering, available in two models: the NetVanta 7060 IP PBX and NetVanta 7100 Unified Communications IP PBX.
The NetVanta 7060 is geared toward small and medium-sized businesses (SMBs), offering support for up to 100 IP phones. The all-in-one box solution is ideal for companies that are looking for a simple and complete VoIP system that won't break the budget.
The NetVanta 7060 includes support for SIP trunking, though the maximum number of SIP trunks is not specified. The Adtran VoIP product also features a built-in multilevel auto attendant supporting complex menus, and voicemail support with eight voicemail ports, which means up to eight users can simultaneously access their voicemail.
The NetVanta 7060 also offers support for two FXS ports, allowing two analog telephones to connect to the system, two FXO trunk ports (for PSTN lines) and two module slots that can be populated with a variety of Voice Interface Modules (VIMs). These include a four-port analog FXO trunk module, a four-port FXS station module (for phones), a T1/PRI trunk module, and a number of other VIM cards.
One of the areas where the Adtran VoIP series falls short is the built-in 24-port power over Ethernet 10/100 Mbps switch. Ten years ago, this would not have been a big problem; but today's networks hardly use 10/100 Mbps switches. And when you consider that most of Adtran's IP phones have a built-in Gigabit Ethernet switch port, you realize the built-in switch is pretty much useless for customers who want to use Gigabit Ethernet.
However, unlike the NetVanta 7060, the 7100 offers a built-in wireless network access controller used to configure and control NetVanta wireless access points. This much-welcomed feature truly confirms this is an all-in-one product for SMBs.
NetVanta series Adtran VoIP products can be managed via the built-in Web interface from any workstation that has direct access to a NetVanta IP PBX.
Adtran IP phones
The Adtran VoIP line also includes a wide range of IP phones and conference stations that should satisfy most users. Most IP phones offer a dual-port Gigabit Ethernet switch port, allowing the simultaneous use of a computer and IP phone through one Gigabit Ethernet port while using 802.1q trunking.
The high-end IP phones offer 12- or 16-line support with a 3.5-inch or 4.3-inch color multi-touch display, and the ability to add a camera to support video conferencing. Lower-end IP phones offer a decent LCD display with two- to six-line support and Fast Ethernet or Gigabit Ethernet support.
Adtran also offers an IP softphone available only on the Windows platform, though users can install almost any SIP-based IP phone on their mobile device.
Adtran VoIP products are available through its official distribution and partner channels. Customers seeking an Adtran solution can also contact Adtran's sales team directly.
