[Asterisk-Users] Will Asterisk be supporting RTCP XR in the future?
This article below came up on the newwire. The RTCP XR RFC was published. Will Asterisk be supporting this function in a future release? Does anyone know if any phone vendors are going to be supporting it? Thanks Lee Goodman Our Technology Update this week is about one of those 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 support problem resolution, or be retrieved from a gateway using SNMP. Administrators can use SNMP to retrieve data from each IP gateway, or use midstream probes or analyzers to capture call-quality data to aid in problem resolution. In addition the set of VoIP performance metrics defined in RTCP XR also form the basis for new draft quality-of-service reporting extensions to leading call-control protocols. This will let IP endpoints report call-quality metrics directly to call managers and softswitches, making integration into call detail records easier, according to our author. I am sure you'll be hearing more about this protocol. For more on this article see: <http://www.nwfusion.com/news/tech/2003/1117techupdate.html>

Yes, if you can get someone to code for this, it would be a pretty cool extension. Just getting normal RTCP in there would be a plus: many hardphones support RTCP (Cisco, Budgetone, Sipura, etc.) and getting some useful data back on each call would be a huge bonus for service providers who need to examine call quality across uncontrolled network segments. Having that stuff in the CDR (or some small subset of it) or in a separate CQDR (call quality detail record) would allow for some very fancy metrics collections. JT
