I'm looking for real world experience related to deploying cRTP header compression on Cisco routers related to VoIP flows. We are trying to evalute what type of hardware (ie: CPU power since cRTP is CEF switched since 12.2x IIRC) is required to handle 96/192/384 VoIP calls over a single circuit (HDLC/PPP/FR). This is related to specific overseas circuits where the cost of the circuit is still very expensive vs the cost for the extra hardware to handle the header compression. I'm disregarding all QoS info at this stage. Cheers Thomas
