Business Class VoIP Technical Considerations
VoIP requires broadband speeds such as ADSL or fixed wireless to achieve the same quality as a traditional copper telephone line.
VoIP quality is directly related to network delay and errors in your Internet connection. These problems might delay an email for a few minutes but with VoIP they cause echo on the line, dropped calls and perhaps one party being unable to hear the other. They can also prevent you from leaving voice messages or entering voice messaging prompts.
Network delay depends on the type of network, the overall distance between caller and receiver, the total number of users on the network, the type of network connection and the equipment used. Network delay can also cause jitter if the VoIP packets are received outside the expected window of time.
Our network design minimizes network delay. The delay between a customer site and our VoIP gateway is under 35 ms. The generally accepted standard is 150 ms.
Compressing VoIP traffic into smaller packets can significantly improve VoIP quality because the smaller packets travel faster. Faster delivery also reduces degradation of the VoIP signal over long distances. Finially, compression optimizes the Internet connection and permits more simultaneous VoIP calls.
