I understand that they both use strict priority queuing and with ip rtp priority, the packets destined for the strict priority queue are identified by the port numbers (parameters to ip rtp priority). If anyone has an opinion why one is *better* than the other, let me know.

Ip rtp will only compress the rtp/udp headers. LLQ is typically used with access lists to specifically prioritze voice udp ports and set the Ip precedence on those ports. Check out the AVVID QoS design guide for config examples. You need 12.1.3T or higher.

Friends, It is right that "ip rtp priority" and LLQ both follow stirct priority queue. Normally "ip rtp priority" is used for real time traffic where as LLQ is used to define the priority status with in CBWFQ and it is not limited to specific ports, as what the case for "ip rtp priority".

Trust this brings needful clarity. Let me have yr email address I have a good stock on QOS.
