Voip Phones - Factors for Quality of Service (QoS)

Signal delivery of voice, video and fax from one point to another cannot be considered done with complete success unless the quality of signals transmitted meets the receiver. Among the factors that affect quality include the following:

Bandwidth requirements, the speed of transmission, network infrastructure, and its physical topology for Voip Phones.

  • Control Functions includes the reservation of resources, provision and monitoring required to establish and maintain multimedia connection.
  • Latency or delay from source to destination of the signal through the network.
  • Jitter variation in arrival times between packets. To minimize this factor incoming packets are to be placed in a buffer and from there sent to standard intervals for Voip Phones.
  • Packet loss: When a packet video or voice is lost in the network must have some kind of compensation of the signal at the receiving end.
