Has anyone deployed VoIP successfully across Qwest's WAN backbone? I have 2 sites connected over Qwest's VPN service (consists of running IPSec over Qwest's MPLS backbone). Qwest says they currently have no QOS support in backbone, but the backbone has huge capacity (OC-192 pipes), which Qwest asserts should support VoIP apps. Round trip ping times across the WAN are typically 50 msec.
I have the traditional VoIP problem of excessive jitter causing poor voice quality. Currently have 2621 routers at each site running WFQ wth Voice packets marked with IP precedence 5 for voice data, and IP precedence 3 for voice control. I am considering re-configuring the routers to run PQ-CBWFQ. If anyone has successfully got VoIP running successfully across this Qwest's backbone, I would be interested in hearing your approach and which config worked. Even though the Qwest WAN has huge capacity, but no QOS support, can it really support real-time apps like VoIP??? thanks, dj FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
