I need to fine tune the QOS on a Point to Point link for video calls. Users are experiencing audio issues during VC call between site A and B. There is voice loss experienced at either ends. we are using cisco sx20, 80 and webex room kits.
I have the below QOS applied to WAN interface, plz let me know if i need to include any to make it more robust.
I am not sure, if the defined BW in policy-map needs to be adjusted for this purpose.
Link BW is 100 Mbps.
Policy Map P2P_VOIP Class L3-to-L2_VoIP-RTP priority 10000 (kbps) Class L3-to-L2_VOIP-Cntrl bandwidth 256 (kbps) Class class-default fair-queue
Class Map match-all L3-to-L2_VoIP-RTP (id 1) Match ip dscp ef (46)
Class Map match-any class-default (id 0) Match any
Class Map match-any L3-to-L2_VOIP-Cntrl (id 2) Match ip dscp af31 (26) Match ip dscp cs3 (24)
