[asterisk-users] tools/techniques/metrics for measurement of end-point quality
Hi, It looks like Voice quality is more and more frequently embedded in phones themselves, mostly with RTCP statistics. I've understood RFC3550 is a first step and RFC3611 goes one step further with MOS and R-factor mesurement. I suppose that best practices should include a way to monitor those Voice quality statistics from a monitoring hub and trigger call routing to improve voice quality when desirable. I'm not aware of any SIP hardphone complying to RFC3611 though a couple of SIP softphones claim to. Among those softphone, I'm aware of Counterpath's eyeBeam (which embed Telchemy VQMon software) and Kapanga. I think I once contacted Telchemy to know SIP hardphone vendors they dealed with but couldn't get any reply. So, that leaves RFC3550 compliant hardphones. I think Cisco's are RFC3550 compliant. Hope this helps ... -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20061003/6280175d/attachment.htm
