QoS for VoIP on Cisco 1760 Routers - Help
Posted on 2004-11-27
I need help setting up QoS on my multi-location WAN routers, that are running VoIP.
I have a VoIP phone system, and we are sharing our 1.54M Frame Relay pipes between the multiple locations for Voice and Data. Our Routers are Cisco 1760s with 1WIC T-1 card each.
Usually there is no issues, but at certain times of the day, callers are reporting dropped packets and crackling. I need to set up QoS to give the Voice priority over all other traffic.
Our phone system is a SoftSwitch made and sold by Sphere Communications, Inc. I do not know what protocols the phone system uses. I do know that the Polycom IP500 IP phones use H.323 and MGCP. I also know that we are currently using the G.711 codec (about 80k per conversation).
Any help you can give would be great. Thanks.
