Hi Erik
I am getting the matched packets on the access-list for the ip packets, but
still when i start the voice conversation between the two boxes, it is not
reserving the 40 Kbps , when the ftp is going on , the traffic reaches to
62 Kbps , and the voice breaks while talking ,pls do suggest what to do.
Rgds
