Incoming calls with CC enabled will not automatically clear the CC offer
record when the call is aborted by T309 processing. All CC agent FSM's
have this problem (PTMP, PTP, and Q.SIG).
To reproduce:
1) Place incoming call to Asterisk/libpri
2) Either before or after the call is answered, bring the ISDN link down.
3) T309 processing, T309 timeout, or TEI removal will leave the CC agent
FSM in the CC available state.
The problem is indicated by the "cc report status" CLI command showing a
status of CC offered to caller but it will never timeout.
The FSM's can be manually cleared by using the "cc cancel all" or "cc
cancel core" CLI commands.

Validate the given call pointer in libpri API calls. If the call pointer
is not an active call record then a complaint message is issued and the
API call aborts. The call pointer is likely stale.
This patch is defensive. More information is needed to figure out why
Asterisk still has a call pointer during its hangup sequence.

The DL-ESTABLISH confirm event was not passed from Q.921 to Q.931 so Q.931
never cancelled the T309 timer.
Refactored q931_dl_tei_removal() and q931_dl_indication() into
q931_dl_event() to allow the DL-ESTABLISH confirm/indication and
DL-RELEASE confirm/indication events to be passed to Q.931.

If the connection to the terminal is lost while there are open channels
on the interface, red alarm is reported, but the open channels are never
cleared. Additionally, if you manually try to channel request hangup,
Asterisk crashes.
For PTMP, the T309 processing was not searching the call pool on the
master control record. Additionally, for NT PTMP, the timeout events were
not passed to the upper layer because the events were not put on the
master control record where timer processing expects them.

Q.921 was passing a q931_dl_indication(up) event to Q.931 before it was
finished processing the frame. The q931_dl_indication(up) event could
immediately send STATUS messages in the Q.921 intermediate state that
would then get stuck in the tx queue with an invalid N(S).
Q.921 was passing i-frames to Q.931 before it was finished processing the
frame. The i-frames could cause Q.931 to immediately generate a response
message that may cause the peer to see the P/F bit as incorrect.
Delayed passing q931_dl_indication(up) events and i-frames to Q.931 until
Q.921 has completed processing the frame event. (The Q.921 SDL diagrams
were designed with this assumption.)

Incoming calls specifying the channel using a slot map could not negotiate
a B channel correctly. Libpri historically has handled this as an any
channel request. However, when chan_dahdi picked a new channel, libpri
sent out the recorded slot map and not the new channel selected. Thus the
two endpoints would be attached to different B channels and the parties
would not hear anything or would hear the wrong parties.
This patch restores the historical preference of sending out the channel
id using the channel number method if a channel number is available.

The switch is sending the Connected Address ie (12) and there was no
handler for that ie. That is why the reporter was getting the "Missing
mandatory ie" message.
The simple fix is to just add the missing receive handler for that ie.
Since connected line (COLP) functionality has been added and this is just
an alternate for the Connected Number ie (0x4C), the handler was already
written. I also changed the ie name to what Q.931 calls it: Connected
Address.
Also some minor code clean up in q931_handle_ie() and ie2str().

The DAHDI driver had a bug where an extra byte appeared on the end of

1) No sent messages will remain in the APDU queue unless they have an
active timer to remove them. The dummy call reference call and global
call reference call structures will not act like a memory leak to sent
messages.
2) The new T-RESPONSE timer will be the generic response guard if the
standards do not otherwise specify a timer for a message response.
3) The callback will be called. If it is called because of a response
message, then the callback has an opportunity to indicate if more
responses are expected.

The facility ie queue needs to remove facilities that have been sent.
Otherwise, the queue just grows until the call is terminated. AOC
messages can clog the queue during a long call and the dummy call

function was not a good idea since many facility messages do not have
responses and the callback would prevents removal of events from the list.
