  • FortiVoice 200D
  • Avaya IP Office 500
  • Cisco UC 320W- FXO-K9

FortiVoice 200D

Fortinet is one of the leading producers of business phone systems offering a series of digital and IP phone systems. In 2013, the FortiVoice 200D was awarded the Unified Communications Solutions Product of the Year by Internet Telephony and Customer magazines.

For smaller sized businesses, the FortiVoice 40, 40S, 70, 100 and 100T will accommodate up to 400 users while maintaining the features of a larger business phone system and costing less. These systems are conveniently compact for a small business.

Features include:

  • There is an embedded SIP (Session Internet Protocol) server for IP extensions plus a LAN Ethernet Connection and USB ports for expansion.
  • 20 Auto Attendant lines in several languages plus directed options for callers.
  • Seamless routing of calls from office to cellphones, home phones and off-site locations.
  • Voice to Email.
  • Dial by name directory.
  • Integrated voicemail, allowing cellphone and desk messages to be bundled together in a single storage space.
  • 8 VoIP lines connecting to local and national sites.
  • Ring Groups - allowing different departments to identify each other by allotting distinctive ringtones to each department.

Although the Fortivoice systems share several features and functions with the Avaya and Cisco systems yet to be discussed, it is the Ring Group feature that distinguishes the FortiVoice system from the others

However, the Fortivoice business phone system does not have any sophisticated function for video and audio conferencing unlike the Avaya IP Office 500.

Avaya IP Office 500

The Avaya IP Office 500, named the Unified Communications Product of the Year by Internet Telephony Magazine, has many features all of which help optimize business collaboration.

The Avaya IP Office series of business phones are designed for small to medium-sized companies. The outstanding feature that distinguishes the Avaya IP Office 500 product from others is its 128 part video and audio conferencing capability with video softphones and conference recording.

The system, compatible with Avaya and Nortel phones, is also highly flexible and can be scaled in accordance with the needs of an expanding business. The Avaya IP Office 500 can connect to almost anywhere.

Like the FVC series, the Avaya IP Office 500 can be used as either a traditional phone system or by utilizing VoIP.

However the Avaya system can use digital, analog, IP and SIP (Session Initiated Protocol) in any permutation, and unlike the FortiVoice and Cisco systems, the voicemail function is free.

Cisco Unified Communications 300 Series

The Cisco Unified Communications 300 series, being compact in structure, is specifically designed for small businesses. The model UC 320W- FXO-K9 accommodates up to 24 users and is licensed for up to 24 phones.

Management of this phone system is carried out via the Web, distinguishing it from the Avaya and Fortivoice systems. Installation is very easy - a setup wizard allows changes, additions and phones to be relocated.

There are wireless access points providing the means for co-workers to connect with each other by voice and data on and off-site. Wireless networking is available on-site.

This system also supports Ethernet WAN, connecting the office to the Internet. There is VLAN (Virtual Local Area Network) support should the business need to expand and/or connect more devices.

Built into the Cisco UC 320W-FXO-K9 is a key system and an IP PBX ( Internet Protocol Private Branch Exchange). Cisco Spa 300 and 500 are the best phones to use with this system.

Like Avaya, this system supports SIP trunking, and like Fortivoice, it also features voice to email and auto attendant. All three systems have voicemail features.

A total of 9 analog telephones can be used with the Cisco Spa 8800 gateway, therefore like Avaya and the FVC series, the Cisco UC 320W -FXO-K9 can support both traditional analog and VoIP phones. 12 PSTN (Public Switch Telephone Network) lines can also be connected.
