As you may have noticed, VoIPSupply.com has recently discontinued sales of the Trixbox Appliance. We will continue to fully support existing Trixbox Appliance customers, but we are focusing our efforts on the PhoneBochs Asterisk Appliance as our recommended hardware solution for users of Asterisk, Trixbox, 3CX and other SIP based communications platforms.

Some of you may be familiar with PhoneBochs, but for those of you who are not, I have put together a basic feature comparison between the Trixbox Appliance and the PhoneBochs Asterisk Appliance. The PhoneBochs Asterisk Appliance offers true “telco grade” build quality and performance and is a suitable server hardware platform for Asterisk/Trixbox installations of all sizes.

Dear Mr. Andrews:

I run a manufacturing facility and we recently implemented trixbox to replace our legacy phone system. We have a four-zone analog paging system that was integrated with our previous phone system. What are my options for paging with trixbox?

Ask Mr. Andrews

“Desktop” paging, whereby you dial a number and all the phones in the dialed call group pick up automatically, go into hands free, and play through their speaker what the caller is saying, is supported on trixbox using a number of IP phones. Snom phones, Grandstream GXP Series Phones, Aastra 480i and 9133i, and Polycom phones all support desktop paging.

A note about setting up desktop paging with Polycom phones:

You MUST provision the phone from a FTP server to
load the Polycom config files, then edit sip.cfg, search for
“alertInfo” and set “voIpProt.SIP.alertInfo.1.value” to equal “Ring
Answer.” Now reboot your phone to load the new config option.

For overhead paging, you can make an Asterisk Extension go to the sound card, and wire its output to a traditional external paging system. You can also get boxes to interface a phone FXO or FXS port directly to a sound system. Examples:

  • Valcom V-2001A
    • connects to an FXO port, so more suitable for interface with PBX or other phone system
  • Viking CPA-7B Paging/Loud Ringing Amplifier
    • Has both FXS and FXO ports.
    • Can connect to a normal ATA FXS port in place of a phone
    • Example: Ethernet – SIP ATA – Viking CPA-7B – paging speakers
    • Other models available with multi-zone paging, etc.
  • Radio Design Labs ST-TC1 Telephone System Coupler
    • Also sold as: Smarthome Product
    • connects to an FXO port, so more suitable for interface with PBX or other phone system
  • Bogen TAMB

A third option for paging is to use an overhead, SIP-enabled speaker manufacturer by Cyberdata. Cyberdata offers a recess mounted, SIP enabled speaker that is PoE powered, and can be setup like a normal extension off your Trixbox system. In this scenario, you could place four speakers in your current paging zones, and assign each zone an extension. You could also group these extensions into a “page all” call group. Cyberdata also makes an amplified version of their speaker system for noisier industrial environments.

Can’t find the right Asterisk-based solution? Don’t have the expertise to manage an open-source phone system?

Thirdlane PBX, an Asterisk management tool, requires no Linux or Asterisk experience to manage and install.

  • Ease of Installation.PBX Manager is a Webmin module and can be installed in minutes without requiring any database or web server software. PBX Manager Installation or upgrade is just a matter of pointing at a URL and clicking install button.
  • Ease of operation. No special knowledge of Linux or Asterisk is required for the operation, so the management functions can be performed by regular staff. PBX Manager Permission’s system can be used for limiting users’ access to the system features as required.
