Internet Radio Phone System Documentation

Backbone’s Internet Talk Radio Phone system is the most versatile, powerful telephone system for radio talk shows and stations that want to engage listeners. No need for expensive handsets or cumbersome rack frames, this scalable, online phone system operates right on your computer screen(s) and into your board. No capital expense, no equipment maintenance, no need for phone lines, and no limit on your number of callers.

Developed specifically for professional Talk, News and Sports Radio stations produced digitally “in the cloud” using our Backbone Radio platform, this software-based phone suite gives your station the freedom to broadcast live from virtually anywhere and stay connected with your listeners in the middle of the action.

System Requirements: OS X 10.7+ with Apple Java 6 and Oracle supplied java 7.x

Network Requirements: A high quality internet connection that is capable of supporting Voice over IP. This is an internet connection with the following characteristics:

Upstream bandwidth 1MB/s

Packet loss < 1% (0.5% preferred)
Round Trip packet transmit time < 200ms
Jitter < 30 ms

UDP and TCP traffic allowed out
ftp allowed out

To test the capability of your internet connection run the 8×8 VoIP test. This test requires a 64-bit browser that supports Java such as Safari. The Chrome browser does not currently support this test.

Network ports out for control/telephony are 5062, 6660-7000 and 9990-9999. If you can’t connect to the phone system, these ports will likely need to be opened on your network by your IT department.

Mix-Minus – For your DJ phone computer — set up a mix minus with your mixing board auxiliary output, and input channel on your board similar to:

Phone System Installation, note that this will need to be done for both the screener and the talent Macintoshes:

  • Start phone client — if OS X asks you to install Java, do so.
  • Then download and install the Oracle Java SE Dev kit 
  • Set your mac audio inputs to be your mix minus audio device (both input and output)

DJ and Screener programs are zero config. Copy the DJ program to DJ/Talk host computer, Screener to screener computer and run them.

If they connect to the hosted cloud phone PBX, you’ll hear a single ring sound and see the interface.

Phone Number: The DJ and Screener programs have your call in phone number with area code in the title.

How to use the Phone System: Either of the two programs DJ and SCREENER can be used independently, or together to allow for call screening. DJ and Screener can be at different locations, anywhere they need to be in the world, as long as there is an internet connection.

As callers dial in to your call in number, they will hear an intro message, and appear in the call list. Here’s how to screen and talk to multiple callers for your talk radio show.

On an individual line:

  • Click ANSWER to talk to/screen a caller.
  • Incoming calls show RING in interface. Screener will speak ‘CALL‘ through default audio interface
  • On SCREENER interface, notes dialog will appear (info entered here will be shown on the DJ interface).
  • Screener notes will be saved for individual caller IDs. ‘Blacklist’ callers to id them later if they call back.
  • SCREENER: Click HOLD to hold call. ANSWER to talk again.
  • DJ: Click AIR to mark call as on air, Click HOLD to hold, ANSWER to talk again.
  • Conference multiple callers together with CONF button.
  • DROP to disconnect caller

  • Click HANGUP ALL to drop all existing calls
  • DIAL pops up a number pad, and allows calls out to be made on individual line (calls can be made anywhere in USA, international available on request, extra charges may apply.)

For communication between DJ and SCREENER, chat in CHAT box to the right of status light in lower lefthand corner.

Configuration parameters, accessed via ‘configuration’ button should not be changed.
