I'm setting up some QOS classes to use with LLQ on some router ports. I've used 95k for each g.711 call in the EF priority queue, but I'm unsure how much bandwidth to use for the call control for each call. We're marking call control at CS3, and the Cisco QoS SRND v3.3 only mentions "150pbs (plus Layer 2 overhead) per phone call of guarandeed bandwidth is required for voice control traffic; more may be required, depending on the call signaling protocol(s) in use."
So for a 100MB ethernet link which 300 VoIP g.711 calls will be traversing, I've 30mb of priority queueing (rounded up) and 60k for call control bandwidth, using 200bps for each call.
Does 200bps per call for call control sound like it will be enough?
