Summary:                    [patch] Asterisk is core dumping with LibPRI
Description: 
We have a system using asterisk 1.4.32 and libpri libpri-1.4.11.4.  I have
attached a backtrace that shows it is failing with libpri.  The logs always
show the following line right before asterisk crahes.

issue_18032_v1.4.patch is against the libpri 1.4 branch
issue_18032_v1.4.11.4.patch is against libpri version 1.4.11.4.

The patch validates the call pointer given by Asterisk.  If the call
pointer is not an active call record a message is issued and the action
requested by Asterisk is ignored.  The call pointer is likely stale.

These patches are defensive.  More information is needed to figure out why
Asterisk seems to be using a stale call pointer.
