Recommended Connectivity for Voice Traffic

Connectivity plays the most critical role in ensuring a quality experience of the Euphoria business communications platform.  Below is a high level guideline for customers to follow when choosing connectivity for voice communications.

Rule #1 – do not share voice and data traffic over the same internet connection

If you do, some or all of the time, the users, will experience:

  • Dropped calls
  • One way audio
  • Increasing and decreasing of volume on the call
  • Break up of the conversation
  • Hearing sounds like people are talking under water

Euphoria Telecom will under no circumstances advise that a broadband Internet connection be used for both voice and data.


Suitable connectivity for sites with 3 to 30 users and less than 8 simultaneous calls

  • Dedicated 1Mb+ Fibre connection with or without ViBE
  • Dedicated 2MB+ ADSL connection used in conjunction with a data traffic connection using ViBE in RAIN mode.
  • Dedicated Telkom LTE connection used in conjunction with a data traffic connection using ViBE in RAIN mode.
  • Dedicated Telkom LTE and 2MB+ and a dedicated ADSL connection used in conjunction with each other using ViBE in RAIN mode.

Suitable connectivity for sites with 30+ users

  • Dedicated 1Mb or greater Fibre connection with or without ViBE and a failover connection.
  • Dedicated Telkom LTE connection used in conjunction with a Fibre data traffic connection using ViBE in RAIN mode.
  • Dedicated Telkom LTE connection used in conjunction with a Microwave data traffic connection using ViBE in RAIN mode.
  • Dedicated Telkom LTE connection used in conjunction with a licensed wireless traffic connection using ViBE in RAIN mode.

An adsl connection is never suitable for sites with more than 30 users – if it is, bad call quality will be experienced by the users some or all of the time.


Unsuitable connections for voice traffic

  • 2G and 3G cellular connectivity are not suitable for reliable voice traffic
  • Unlicensed wireless connectivity is subject to interference which affects call quality.
  • Congested or over contended networks of any type (including over Fibre, Wireless, LTE or ADSL)  will result in bad call quality.
  • Any connections with not enough bandwidth available to manage the peak throughput of voice traffic.
  • A congested or badly managed local area network or LAN (office network), will result in bad call quality.
  • Standard WiFi is not suitable for voice traffic, for WiFi to work in an office environment for voice traffic, a professional mesh WiFI installation would need to be done ensuring there is enough signal strength and throughput for voice and data traffic.
