Successful VOIP Over DSL, Part 2: What is QoS?
You hear an awful lot about “QoS, which stands for “Quality Of Service.” In point of fact it means different things to different people depending upon their perspective, telco or IP networking.
Successful VOIP Over DSL, Part 1: Some Installation Basics
Here are a few fundamental considerations when planning a VOIP implementation using DSL.
- What is your actual available bandwidth inbound & outbound?
- How many simultaneous calls do you need to sustain?
- What voice codecs are you using? And so, how much total bandwidth do you require?
- Do you have managed QoS on your network?
- Can you also implement traffic shaping to reserve bandwidth for VOIP purposes? Especially outbound bandwidth as this is typically the most scarce.
