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.
