Summary:                    [patch] No inband progress on PRI_EVENT_RINGING even
if inband flag set
Description: 
My ISDN-PRI provider sends a ALERTING with "Inband information or
appropriate pattern now available", but Asterisk only generates and passes
the ring to the SIP extension, not the inband message.
Unfortunately, the inband message is not an actual RING, but a prompt that
says the number is not in service. So, the SIP receives two rings and then
a hangup, confusing the agent using the SIP extension.

I have attached pri_debug.txt - this is after the patch was applied, but I
don't think it makes much differentce. Also, sorry for the bad category of
the bug, it should be chan_dahdi.

I do have another provider that handles the call setup well: SETUP -
PROCEEDING - PROGRESS - ALERTING - DISCONNECT. So maybe we can do a
per-span configuration entry for using the inband of ALERTING or not?
