Independently of any mobile phone applications, there are known to be at least 
50 million devices (in reality closer to 200 million) and over 100 equipment 
vendors that have the capability of reporting RTCP XR, and a fair number that 
also use the SIP RTCP Summary Reporting draft.  These include IP phones from 
two tier 1 telecom equipment providers, softphones, residential and trunking 
gateways, and MTA's (cable industry).  Also Texas Instruments incorporated 
support for RTCP XR into all of their VoIP solutions.

In addition to the RTCP XR VoIP metrics being adopted as part of H.323, they 
were also incorporated into H.248 (Megaco) and into PacketCable 1.5.
