What is VoIP, exactly?

The term VoIP completes as Voice over IP (Internet Protocol), which is system of making your calls using your internet connection, rather than the traditional phone networks. It is estimated that by the year 2025, the traditional landline system will be completely obsolete, and replaced by VoIP.

VoIP is already the dominant communication system in many businesses across the world. The biggest challenge to successful implementation of VoIP in a business is the internet speed available. But with many Internet Service Providers now being able to provide blazing fast internet speeds, VoIP implementation becomes inevitable as the integral business communications system.

Bandwidth – How much bandwidth do you need for our VoIP solution?

Bandwidth is the amount of data your internet connection can send and receive in a certain period of time, measured in kilobytes per second.

Before we deploy voice-over-IP service in your office, we first address how much bandwidth you have and how it currently used. On top of that we look at the switches and routers, battery backup equipment used in your office. This is because Voice over IP needs a certain amount of minimum bandwidth in order to keep your conversations very clear and free of disruptions.  The key voice-over-IP requirements we consolidate are;

  • Bandwidth – determining your bandwidth needs for voice-over-IP in your office.
  • The Router – the performance of your router can upgrade or degrade your call quality
  • Quality of Service – power to separate voice traffic from regular internet users
  • VoIP Equipment – quality of VoIP phones, soft phones, headsets and telephone adapters used
  • Power Backup – Installing a battery backup system or a Power-over-Ethernet switch to keep VoIP powered

Calculating the bandwidth you will need

  • Full Quality Audio (G711 Codec)\- uses 87 kbps for each concurrent phone call (NEB)
  • Compressed Audio (G729 Codec)\- Uses 33 kbps for each concurrent phone call (NEB)

So the calculation for a typical DSL connection would be;

  • DSL connection:600 kbps upload / 5000 kbps download
  • Gives us (Full Quality):600 kbps / 87 kbps = 6 concurrent calls
  • Gives us (Compressed Quality):600 kbps / 33 kbps = 18 concurrent calls

Nextel integrates the best Internet Service Providers locally, and sources international bandwidth providers to provide leased line connections that facilitate high bandwidth needs of a modern voice communications setup. We perform the necessary due diligence end-to-end and design networks that guarantee a lossless VoIP experience.
