...to determine the location of the problem. I.E. An RTP/IAX "traceroute" tool. What I'm hoping to find is something that either integrates directly with *, or captures live RTP/IAX traffic and provides real time statistics on calls.

...mechanisms. Known as RTP Control Protocol Reporting Extensions (RTCP XR), the technology defines a standard way to detect VoIP call quality by monitoring a variety of key call ingredients such as packet loss, delay and call quality. According to our Technology Update author ( <mailto:alan@telchemy.com> ), the IETF this month published RTCP XR as RFC 3611. In a nutshell, our author says RTCP XR works by exchanging messages containing key call-quality-related metrics are periodically between IP phones and gateways. This lets a probe or analyzer monitor these metrics midstream to suppor...
