Hi all, I'm looking at deploying Cisco routers in front of 3CX, so I wonder if any of you have had experience of these (I assume so, given the numbers here). My question relates to QoS. Cisco in their flavours of IOS give you several options for the configuration of QoS. These range from DSCP (ToS), EF bit setting, MQC, WRED, and various other TLAs I *think* i've identified NBAR as the QoS tool of choice for the RTP protocol, and the priority-list command as the QoS tool of choice for other protocols such as SIP signalling etc. My question is - is this the best way of doing things? or do people have other ideas? I assume the most important configuration would be NBAR because then I can identify and provide QoS to the RTP protocol which provides the voice streams (and very little else seems to be able to do so). All input is valuable! Cheers, Mike.
