there is another method, see previous post on this list:
https://puck.nether.net/pipermail/cisco-voip/2008-July/035519.html

For an SCCP phone the statistics come out in the 
StationConnectionStatisticsResponse.  The rest of the math is the same 
with regards to packets per second, bytes, etc.


What is the remote device in your case?

Regards,
Wes
