I am new to QOS so please bear with me.
This is a very basic sketch of my network.
Multiple remote sites ------> WAN <------ 2800 <-----ASA 5510 <----- 2960(G) ---[ LAN with BCM400.
I have started using VOIP between some locations but I am concerned about the implications of not having QOS network wide.
1. Should I configure QOS on every device (2800, ASA 2960(G) switches etc)?
2. 20 Remote sites will each have a max of 2 IP/Softphone (Nortel & Cisco) and has 1mb down and atleast 256kbps upload speeds how would you recommend we allocate bandwidth for VOIP?
N.B codec: cisco g729 and nortel g711.
If i am missing anything please help!
If I have to configured QOS on each device
