Providing recorded information to callers that is updated regularly or just one off recordings works well, but there are times when you need a live audio stream to be played to a differing quantity of callers on your line. Using our broadcasting services you can connect live feeds directly into our system to transmit up to 240 live feeds of 8K audio at any time.

Live feeds are available by using one of the following mediums:

  • Leased line connections
  • Direct Copper/Fibre Connections
  • Radio (microwave) connections
  • Satellite Connections
  • GSM/PCM Connections
  • Frame Relay IP Connections

If you are not using an IP connection we can just support the regular phone line if needed. Once connected we can arrange your feed to be either a temporary or permanent arrangement.

Network Interfacing

If you're connecting your live audio feed into our system, we can support the following Signalling Capabilities:

  • " VoIP (H.323 with H.245, Q.931, G.732.1, G.711, G.729.a, voice and data G.726, GSM) network protocols. All protocols are considered standard with " SS7 mature signalling interfaces."
  • Digital (Full and fractional E1/T1, ISDN, R1/R2)
  • We also support Analogue and International Protocol Conversion for when it is needed by your application.
  • A simple "Line Level" -10DB audio screened audio signal that your equipment must comply with provides standard audio input into our system.

External Input

If needed we also have available an external input server which will allow us to connect an I/O device over a medium like a leased line, the internet, SMS, radio or any way of getting a switch output to us. This can be used to change around recordings or simply disable/enable your line when you want to. Some customers already using this incorporate this feature for a weather system so events can be cancelled/re-opened based on links provided by the MET office.

The external input feature offers voltage free (dry) contacts with NO/NC circuitry if needed. For heavy loads (over 1VA) a contactor is supplied free.
