You didn't say which version you were running. Does the problem still occur
with the latest version from svn trunk?

I assume there is a SIP service provider somewhere between your FreeSWITCH
system and the PSTN. It is quite possible that the problem is on their end,
especially if their system is terminating the calls. From the logs, it just
looks like a standard hangup, which leads me to wonder whether the other side
is responsible.

Collecting SIP traces would seem to be a good idea.
