Richard Mudgett	f8e6096bfe	q931.c: Lucent switch implementation bug workaround (Part 2) Work around a bug in a Lucent switch implementation that sets the extension bit in octet 3 even though octet 3a is present. The same issue was seen in a NI2 switch implementation. It was probably a Lucent switch configured for NI2 operation. To avoid further surprises, I'm going to enable the work around for all North American switch types.

Richard Mudgett	d2585d6da2	q931.c: Lucent switch implementation bug workaround. A bug in a Lucent switch implementation sets the Connected Number information element octet 3 extension bit. When set that means octet 3 is complete and thus there is no optional octet 3a. However, the buggy switch still sends octet 3a. The unexpected octet 3a is interpreted as the first octet 4 and thus the first character in the connected line number is a garbage character. * Work around the switch bug by checking octet 3 and the potential octet 3a extension bits. If they are both set then assume that octet 3a is actually present for the buggy switch types.

Richard Mudgett	2952e95715	q931.c: Fix DISCONNECT Progress Indicator ie handling. There are two scenarios that are exposed by DISCONNECT not initializing the progress indicator value before processing the message when the chan_dahdi.conf inbanddisconnect=yes option is set. 1) If a DISCONNECT comes in without a Progress Indicator ie and an earlier message (such as SETUP-ACKNOWLEDGE or PROCEEDING) came in with the indicator #8 (Inband audio present) then the DISCONNECT would not cause an immediate hangup. We would be letting the user hear the inband audio even though there isn't any. 2) If a DISCONNECT message comes in with the indicator #8 (Inband audio present) and then later the DISCONNECT message is repeated without a Progress Indicator ie we would still ignore the second DISCONNECT to let the user hear inband audio even though it likely isn't there anymore.

Richard Mudgett	998e6ba598	Adjust T202 default value to the minimum. The minimum T202 time specified in Q.921 Section 5.9.7 is 2 seconds. It makes sense to set the value to the minimum 2 seconds in order to more likely get a TEI value before an outgoing call request aborts from T303 timeouts.

Richard Mudgett	cfac266390	libpri: Add control of inband audio progress indication ie to the SETUP_ACKNOWLEDGE message. Added support to the libpri API to control the inband audio available progress indication ie on the SETUP_ACKNOWLEDGE message. * Added the progress indication ie progressmask value to the struct pri_event_setup_ack so the PRI_EVENT_SETUP_ACK event can indicate when a SETUP_ACKNOWLEDGE comes in with inband audio (ie dialtone). * Added pri_setup_ack() so when the SETUP_ACKNOWLEDGE message is sent it can indicate if inband audio is present (ie dialtone). This patch and a corresponding change in Asterisk work together to allow Asterisk to control the inband audio available progress indication ie on the SETUP_ACKNOWLEDGE message when dialtone is present.

Richard Mudgett	13beaacc80	libpri: Make TE-PTP mode respond to MDL TEI check requests. Some BRI devices in France insist on checking TEI's when in point-to-point mode. If they don't get a response for TEI 0 they drop layer 1 even though libpri keeps trying to bring layer 2 up. * Made q921_mdl_receive() handle TEI check request messages in TE-PTP mode. Had to change q921_mdl_send()/Q921_INIT() because the PTP modes do not setup a link structure specifically for MDL as the PTMP modes do. * Fixed q921_tei_check()/t201_expire() to check TEI's even if the network side doesn't have any assigned. This should make TE's that request the TEI verify procedure (Q.921 Section 5.3.5) happy when the network side doesn't have any TEI's allocated.

Richard Mudgett	84b2560da5	Fix hole in layer2_persistence option for TE PTMP links. If the network stops responding, according to Q.921 we are supposed to remove the TEI. With the layer2_persistence option enabled, we are supposed to keep trying to bring layer 2 back up. Unfortunately, when the network stops responding, we stopped the restart timer and removed the TEI. As a result, layer 2 does not immediately come back up. * Made not stop the restart timer if we are removing the TEI on the CPE side. Also handle the timer expiration in relevant unassigned TEI states.
