I am setting up a Call manager phone system in a network that uses a Cat 4006 as the core switch. The 4232 blade is doing VLAN routing to a number of IDFs using port channel interfaces. I would like to know if there are any recommendations for changing the default qos mappings or setting any traffic conditioning at the port level that I should apply by default.

I was wondering if cisco had any recommendations for changing this in voice enabled network or if anyone had any opinions based on experience.
Please let me know if my understanding of the situation is wrong.

No. You will only need the SRST licenses on the primary router. Because this feature...
