[Serusers] Checking Active Calls

[Ryan Pagquil]

Hi,
	I'm implementing SER in a prepaid environment. Now we are getting 
active calls from the radacct tables of RADIUS since we are using 
RADIUS auth and acct. We are just assuming that those entries without 
an acctstoptime and sessiontime are active calls. Is there a way for 
me monitor if the call (entry in the radacct table) is really active? 
Or is there any tool that I can use to monitor active RTP sessions 
from gateway to UA?

Thanks,
Ryan
