053a38202e Removed MDL/TEI management configuration warning message.
Some telco switches send out MDL messages even though they are configured
for PTP.  Usually they are checking for assigned TEI's.  Since these
switches periodically poll for assigned TEI's, the message needlessly
fills up log files.

* Changed message warning level to a normal debug message level and
reworded.

fffb7babaf Implement T316 to allow RESTART messages to be automatically retransmitted.
Q.931 defines the T316 timer to retransmit RESTART messages if a RESTART
ACKNOWLEDGE message is not received before the timer expires.  Q.931
defaults the time of T316 to 2 minutes with the default number of
consecutive RESTART failures as two.

* To support legacy behavior, the T316 timer is disabled by default.  It
is also disabled because the user cannot configure it to disabled if it is
enabled.

* The N316 count is created to allow the number of RESTART attempts to be
configurable.  Note you will need to recompile Asterisk to be able to
configure N316.

a7eaec1aaa Make number not available presentation also set screening to network provided.
Q.951 indicates that when the presentation indicator is "Number not
available due to interworking" for a number then the screening indicator
field should be "Network provided".

Released versions of Asterisk starting with v1.8 relesed before this patch
only recognized the PRES_NUMBER_NOT_AVAILABLE value as an unavailable
number.  This patch improves compatibility as a result.

* Made mask the presentation value for names and numbers from the upper
layer.

* Made pri_mwi_indicate_v2() also call q931_party_id_fixup() for
completeness even though it is a noop in this case.

* Made pri_pres2str() deceoode better.

6078b21698 Remove nul octets from IE data that is normally treated as strings.
Sometimes ie values received from carriers contain nul octets in values
normally treated by libpri as nul terminated strings.  A discussion on the
asterisk-users list determined that the best thing to do in the situation
is to delete the nul octets and unconditionally report/log when that
happens.

* Remove nul octets from the following ie's and generate an unconditional
log message to the upper layer when they are removed:
Connected Number
Connected Address
Redirecting Number
Original Called Number
Redirection Number
Called Party Number
Calling Party Number
Display

4e7c3d1462 Implement handling a multi-channel RESTART request.
The channel id ie can supply a slotmap or list of channels.  For a RESTART
message, this can be handy to indicate multiple channels that need to be
restarted at the same time.

An incoming RESTART request will now generate a PRI_EVENT_RESTART to the
upper layer for each channel indicated in the request.  If the event is
successfully generated for all indicated channels then a
RESTART_ACKNOWLEDGE is sent back to the peer indicating all channels
restarted.

* Add the ability to process a channel id ie channel list with a RESTART
request.

* Add the ability to process slotmaps with a RESTART request.

c5ec479bd2 Outgoing BRI calls fail when using Asterisk 1.8 with HA8, HB8, and B410P cards.
France Telecom brings layer 2 and layer 1 down on BRI lines when the line
is idle.  When layer 1 goes down Asterisk cannot make outgoing calls and
the HA8 and HB8 cards also get IRQ misses.

The inability to make outgoing calls is because the line is in red alarm
and Asterisk will not make calls over a line it considers unavailable.
The IRQ misses for the HA8 and HB8 card are because the hardware is
switching clock sources from the line which just brought layer 1 down to
internal timing.

There is a DAHDI option for the B410P card to not tell Asterisk that layer
1 went down so Asterisk will allow outgoing calls: "modprobe wcb4xxp
teignored=1".  There is a similar DAHDI option for the HA8 and HB8 cards:
"modprobe wctdm24xxp bri_teignored=1".  Unfortunately that will not clear
up the IRQ misses when the telco brings layer 1 down.

* Add layer 2 persistence option to customize the layer 2 behavior on BRI
PTMP lines.  The new option has three settings: 1) Use libpri default
layer 2 setting.  2) Keep layer 2 up.  Bring layer 2 back up when the peer
brings it down.  3) Leave layer 2 down when the peer brings it down.
Layer 2 will be brought up as needed for outgoing calls.

239f8186ef Problems with ISDN MWI to phones.
1) The "controlling user number" is always the number of the voice mail box
which is identical with the subscriber number itself.  This number which
is listed in the ISDN phone MWI menu cannot be called back to contact the
voice mail box.  The controlling user number should be made configurable.

2) The MWI indication is not restricted to a user (broadcast facility with
dummy call reference).  A called party IE should be added to address only
the relevant MSN.  (ETSI 300-196 Section 8.3.2.4)

e7a5d0da62 B channel lost by incoming call in BRI NT PTMP mode.
A phone's RELEASE_COMPLETE as a response to an initial broadcast SETUP
blocks one B channel permantly when the call is cancelled.

Scenario: A call to the ISDN Bus is acknowledged (ALERTING) by one
phone/endpoint and rejected by another phone/endpoint with a
RELEASE_COMPLETE.  The call is then cancelled by the caller.  If the whole
procedure is repeated once again then any further call attempt is rejected
(WARNING[5666]: app_dial.c:1546 dial_exec_full: Unable to create channel
of type 'DAHDI' (cause 34 - Circuit/channel congestion)).  It seems that
receiving a RELEASE_COMPLETE in that state blocks one B channel
permanently when the call is cancelled by the caller.

Background: The ISDN phones (Siemens Gigaset 3035 or CX253) we use for
testing additionally contain a DECT base station, which operates as a
different endpoint on the ISDN Bus (TEI).  If the DECT base station is not
in use then there are no DECT phones registered to the base station.  The
DECT base station responds to an incoming call not directed toward it with
(RELEASE_COMPLETE, cause: no user responding).

* Made initiate_hangup_if_needed() also hangup the subcall if it is in the
NULL state.

* Simplified q931_set_subcall_winner().

2867fc717e Crash if NFAS swaps D channels on a call with an active timer.
If a Q.931 call record related timer is started on one NFAS D channel
expires after NFAS swaps to another D channel, then libpri could crash.

For example:
1) Hangup a call.
1a) Send a DISCONNECT.
1b) Start the T305 retransmit timer on the current D channel.
2) The RELEASE comes in on another D channel.
2a) The found call record switches its assignment to the new D channel.
2b) Attempt to stop T305.  Unfortunately, the timer was started on another
    D channel so the attempt does not find the timer to stop.
3) The hangup sequence continues normally and the call record is freed
   since there is only one call record pool.
4) T305 expires on the original D channel and crashes the system when it
   uses the stale call record pointer it has saved.

Made each D channel timer pool have a unique range of valid timer
identifiers.  If a given timer identifier is not in the range for the
current NFAS D channel, then search the D channel group for the original D
channel.

For PTP links, libpri generated the PRI_EVENT_DCHAN_DOWN event every time
it failed to bring layer 2 up because the physical layer is down.

For PTP links, made generate the PRI_EVENT_DCHAN_UP/PRI_EVENT_DCHAN_DOWN
only when it enters/exits the Q.921 superstate consisting of states
7(Q921_MULTI_FRAME_ESTABLISHED) and 8(Q921_TIMER_RECOVERY).

Also changed the PTP link restart delay to be link specific instead of D
channel specific because the GR-303 PTP switch types have more than one
Q.921 link.

12805eb71f SABME flood on backup D-channel in NFAS configuration.
Made delay restarting the PTP layer 2 link by the T200 time instead of
immediately.  Q.921 does not specify any particular time to restart the
layer 2 link.  Q.921 leaves it up to the upper layers to decide when or if
another attempt to bring layer 2 up is made.  Earlier versions of libpri
used the T200 time to restart the link.

This is a reimplementaion of -r1878.

d2984ee7eb Minor MDL handler changes.
* Clear mdl_error in case we could not schedule the handler callback.

* Change MDL handlers to not return the handled state since the caller did
not care.

* We should send the TEI identity denied message with TEI=127 when the TEI
pool is exhausted.

* We should remove our TEI if we see a TEI identity assign message
assigning our TEI to someone else.

948625318a Remove all TEIs when NT PTMP starts.
Remove all TEIs when a NT PTMP link is started and there are no other
links to make sure there are no devices that think they have a TEI.  A
device may think it has a TEI if the upper layer program is restarted or
the system reboots.

33aafe9b5a B410P gets incoming call packets on ISDN but Asterisk doesn't see the call.
The Cisco 1751 with VIC 2-BRI ports sends out SETUP messages on the
broadcast TEI as if the BRI were PTMP even though it is configured for PTP
mode.

Make PTP mode also accept frames on SAPI=0, TEI=127 (Broadcast).

7f55b600e0 Fixes CC agents not automatically clearing if T309 clears the original call.
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.

5923df047d Partial support for dynamic interfaces with NFAS.
To have some support for dynamic interfaces, the master NFAS D channel
control structure will always exist even if it is abandoned/deleted by the
upper layer.  The master/slave pointers ensure that the correct master
will be used.

Some code is now simplified since there is only one D channel control
structure and the amount of allocated memory is reduced.

53c142990f Restructure the Q.931 call record to layer 2 link association.
This is in anticipation of extracting a layer 2 link structure out of

Also completes fixing timer value access for the rest of libpri.  The
timer access must always be on the D channel control structure (Master).

May have fixed some events from timeouts not being passed to the upper
layer.  The timeout events must always be on the D channel control
structure (Master).
