Summary:                    PTP MDL can't handle error of type A
Description: 
After a version upgrade of Asterisk/Libpri/DAHDI error messages are
sometimes seen on the connection to a Panasonic PBX.

---------------------------------------------------------------------- 
It looks like a bug in the PBX exposed by the new version of libpri. 
MDL-ERROR (A) is just letting you know that a Receiver Ready packet was
received with the F bit set when it should not be set.  The only
consequence of a MDL-ERROR (A) is the logging of the diagnostic message.

The next version of libpri (1.4.11.4 and 1.4.12 beta2) will reduce the
severity level of the MDL-ERROR (A) message.  It will no longer be logged
as an ERROR level but just as a normal log message.  The can't handle error
of type X message will no longer happen for the defined MDL-ERROR messages
that libpri detects.  You were only getting that message because of the
MDL-ERROR (A) message.
