Summary:                    Q931 inband information not interpreted as alerting
signal
Description: 
We received reports from a customer that they were not hearing a ring tone
when making calls to certain extensions in their office even though the
extension was ringing.

Further investigation showed that this occurred when calls were made to
non-isdn extensions through one particular exchange. In this scenario
inband information is received from the network in the PROGRESS signal
which should be interpreted as an ALERTING signal.

The libpri implementation of Q931 does not accommodate this scenario.
