This problem has continued even after an upgrade to Asterisk 1.2.12, 
Zaptel 1.2.9, and libpri 1.2.3.  All of the debugging so far (SIP and 
intense PRI) have only confirmed that the Asterisk box is the initiator 
of the disconnect request.  In all cases I've reviewed so far, the 
Asterisk system initiates a disconnect on the PRI channel followed by 
sending a BYE request to the SIP party.

The system has currently been taken out of service due to the frequency 
of calls being randomly terminated.  Any suggestions or ideas on how to 
isolate the cause/source of the disconnects would be most appreciated.
