Asterisk 10.2.0-rc2 Now Available
Asterisk The Open Source PBX & Telephony Platform
The Asterisk Development Team is pleased to announce the second release candidate of Asterisk 10.2.0. This release candidate is available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/
The release of Asterisk 10.2.0-rc2 resolves several issues reported by the community and would have not been possible without your participation.
Thank you!
The following is a sample of the issues resolved in this release candidate:
- Fix deadlocks occuring in chan_agent.Bad locking order was added to chan_agent to prevent a segfault that occurred due to a race condition. This patch addresses the bad locking order by locking
the channel and its private data in the correct order. This stops the deadlock, which occurred when doing multiple interactions with agents. (closes issue ASTERISK-19285) Reported by: Alex Villacis Lasso - Include iLBC source code for distribution with AsteriskClarification regarding the iLBC source code was provided by Google, and the appropriate licenses have been included in the codecs/ilbc folder.
(closes issue: ASTERISK-18943) Reporter: Leif Madsen - Fix crash from bridge channel hangup race condition in ConfBridgeThis patch addresses two issues in ConfBridge and the channel bridge layer:
1. It fixes a race condition wherein the bridge channel could be hung up
2. It removes the deadlock avoidance from the bridging layer and makes the bridge_pvt an ao2 ref counted object
(issue ASTERISK-18988, ASTERISK-18885, ASTERISK-19100)
Reported by: Dmitry Melekhov, Alexander Akimov - Don’t do a DNS lookup on an outbound REGISTER host if there is an outbound proxy configured.
(closes issue ASTERISK-16550) reported by: Olle Johansson - Create and initialize udptl only when a dialog negotiates for image mediaPrior to this patch, the udptl struct was allocated and initialized when a dialog was associated with a peer that supported T.38, when a new SIP channel was allocated, or when an INVITE request was received. This resulted in any dialog associated with a peer that supported T.38 having udptl support assigned to it, including the UDP ports needed for communication. This patch creates and initializes the udptl structure only when the SDP for a dialog specifies that image media is supported, or when Asterisk indicates that a dialog needs to support T.38.
(closes issue ASTERISK-16698, ASTERISK-16794)
Reported by: under, Elazar; Tested by: Stefan Schmidt - Allow only one thread at time to do Asterisk cleanup/shutdownAdd locking around the really-really-quit part of the core stop/restart part. Previously more than one thread could be called to do cleanup, causing atexit handlers to be run multiple times, in turn causing segfaults. (issue ASTERISK-18883)
Patch by: Walter Doekes - Fix outbound DTMF for inband mode in chan_ooh323This tells asterisk core to generate DTMF sounds. (Closes issue ASTERISK-19233) Reported by: Matt Behrens Patches:

Asterisk 1.8.7.0 Now Available
Asterisk The Open Source PBX & Telephony Platform
The Asterisk Development Team announces the release of Asterisk 1.8.7.0. This release is available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/
The release of Asterisk 1.8.7.0 resolves several issues reported by the community and would have not been possible without your participation.
Thank you!
Please note that a significant numbers of changes and fixes have gone into features.c in this release (call parking, built-in transfers, call pickup, etc.).
NOTE:
Recently, we were notified that the mechanism included in our Asterisk source code releases to download and build support for the iLBC codec had stopped working correctly; a little investigation revealed that this occurred because of some changes on the ilbcfreeware.org website. These changes occurred as a result of Google’s acquisition of GIPS, who produced (and provided licenses for) the
iLBC codec.
If you are a user of Asterisk and iLBC together, and you’ve already executed a license agreement with GIPS, we believe you can continue using iLBC with Asterisk. If you are a user of Asterisk and iLBC together, but you had not executed a license agreement with GIPS, we encourage you to research the situation and consult with your own legal representatives to determine what actions you may want to take (or avoid taking).
More information is available on the Asterisk blog:
http://blogs.asterisk.org/2011/09/19/ilbc-support-in-asterisk-after-goog…
The following is a sample of the issues resolved in this release:
- Added the ‘storesipcause’ option to sip.conf to allow the user to disable the setting of HASH(SIP_CAUSE,) on the channel. Having chan_sip set HASH(SIP_CAUSE,) on the channel carries a significant performance penalty because of the usage of the MASTER_CHANNEL() dialplan function.We’ve decided to disable this feature by default in future 1.8 versions. This would be an unexpected behavior change for anyone depending on that SIP_CAUSE update in their dialplan. Please refer to the asterisk-dev mailing list more information:http://lists.digium.com/pipermail/asterisk-dev/2011-August/050626.html
- Significant fixes and improvements to parking lots.
(Closes issues ASTERISK-17183, ASTERISK-17870, ASTERISK-17430, ASTERISK-17452, ASTERISK-17452, ASTERISK-15792. Reported by: David Cabrejos, Remi Quezada, Philippe Lindheimer, David Woolley, Mat Murdock. Patched by: rmudgett) - Numerous issues have been reported for deadlocks that are caused by a blocking read in res_timing_timerfd on a file descriptor that will never be written to. A change to Asterisk adds some checks to make sure that the timerfd is both valid and armed before calling read(). Should fix: ASTERISK-18142, ASTERISK-18197, ASTERISK-18166 and possibly others.
(In essence, this change should make res_timing_timerfd usable.) - Resolve segfault when publishing device states via XMPP and not connected.
(Closes issue ASTERISK-18078. Reported, patched by: Michael L. Young. Tested by Jonathan Rose) - Refresh peer address if DNS unavailable at peer creation.
(Closes issue ASTERISK-18000) - Fix the missing DAHDI channels when using the newer chan_dahdi.conf sections for channel configuration.
(Closes issue ASTERISK-18496. Reported by Sean Darcy. Patched by Richard Mudgett) - Remove unnecessary libpri dependency checks in the configure script.
(Closes issue ASTERISK-18535. Reported by Michael Keuter. Patched by Richard Mudgett) - Update get_ilbc_source.sh script to work again.
(Closes issue ASTERISK-18412)

iLBC support in Asterisk after Google’s acquisition of GIPS
Recently, we were notified that the mechanism included in our Asterisk source code releases to download and build support for the iLBC codec had stopped working correctly; a little investigation revealed that this occurred because of some changes on the ilbcfreeware.org website. These changes occurred as result of Google’s acquisition of GIPS, who produced (and provided licenses for) the iLBC codec.
We’ve determined that the change necessary to fix Asterisk’s iLBC build process is rather trivial, and so we’re planning to make that change in Asterisk 1.8.7.0-rc2, and subsequently in 1.8.7.0. We are not planning on making new releases of Asterisk 1.4 and Asterisk 1.6.2, since they are in security-maintenance mode and this is not a security issue. Users who wish to make the same change on their own to their copies of those versions are of course welcome to do so.
As part of the process of determining what had broken here, we also became aware that the ilbcfreeware.org website no longer offers the iLBC license agreement it used to offer; this agreement was required by the iLBC licensors (GIPS) in order for users to safely distribute and use iLBC (and this is why the Asterisk project does not include the iLBC source code directly with Asterisk). The removal of this license agreement also occurred as a result of the Google acquisition, but as of this moment no alternative has been made available for those who wish to use the iLBC source code published in RFC 3951 (which Asterisk uses).
Google does have an alternative implementation of iLBC available as part of the WebRTC project, with a license that is compatible with Asterisk (and does not require written agreements from end users), but the codec_ilbc module in Asterisk cannot be built against the WebRTC implementation of iLBC. Until such time as we have an improved version of codec_ilbc, Asterisk users will have to continue using the RFC 3951 iLBC source code.
Unfortunately, that leaves Asterisk users in a bit of a bind; if they had already signed and sent in the GIPS iLBC license agreement, we believe they can continue to safely use the existing iLBC implementation. New users, though, do not have the option of agreeing to a license agreement that would allow them to use the RFC 3951 iLBC source code, as there is no mechanism to do that currently available.
We’ve contacted Google and they are aware of the dilemma, and have said that they will address it, but we don’t have a timeframe for when an alternative license mechanism will be available.
In summary, if you are a user of Asterisk and iLBC together, and you’ve already executed a license agreement with GIPS, we believe you can continue using iLBC with Asterisk. If you are a user of Asterisk and iLBC together, but you had not executed a license agreement with GIPS, we encourage you to research the situation and consult with your own legal representatives to determine what actions you may want to take (or avoid taking).
