I have a network with Cisco 7960 VoIP Phones, Call manager 3.1 and the access switches are 3500 XL series switches. All my Voice Calls are Chopping up and I need some assistance. I believe it might be QoS however does anyone have any sugjestions to fix the choppiness?
IOS Version: c3500XL-c3h2s-mz.120-5.WC3b.bin
