If murf sends a report to asterisk-dev, you can safely assume there's a leak somewhere.
I've heard about this, but have not experienced it myself.

Steve, I would duplicate the system and run SIPP with a large number of calls. It's easy to check
how many RTP sessions you should have - there are four ports per audio call. If "sip show channels"
show 100 calls, you should have 200 inbound ports open for listening and 200 ports used for sending stuff.
In addition to this you have the usual ports, but those are not many.

If we have a file leak, it's worth tracking it down. From the ports reported, it sure smells like RTP/RTCP ports.
