QoS Parameters to consider when setting the SLAs for VOIP Networks

Am currently working on a draft SLA (Service Level Agreement) with a VOIP carrier, here is a useful link i came across to guide me in setting the maximum allowed values, for both the transmission links and the end to end voice calls.

Things to consider are:

  • Latency: Delay for packet delivery
  • Jitter: Variations in delay of packet delivery
  • Packet loss: Too much traffic in the network causes the network to drop packets
  • Burstiness of Loss and Jitter: Loss and Discards (due to jitter) tend to occur in bursts
