r366547 introduced a change to the directmedia ACL for chan_sip which modified the behavior significantly. Prior to the patch, this option would bridge peers with directmedia if a peer's IP address matched its own directmedia ACL. After that patch, the peer would check the bridged peer's ACL instead. This change has been present since 1.8.14.0. That patched failed to document the change in Upgrade.txt, so this patch adds mention of that change to UPGRADE.txt (UPGRADE-1.8.txt in newer branches) (issue AST-876) ........

===========================================================
|
|
|
|
From 1.8.13 to 1.8.14:
|
|
* permitdirectmedia/denydirectmedia now controls whether peers can be
|
|
bridged via directmedia by comparing the ACL to the bridging peer's
|
|
address rather than its own address.
|
|
|
|
From 1.8.12 to 1.8.13:
|
|
* The complex processor detection and optimization has been removed from
|
|
the makefile in favor of using native optimization suppport when available.
|
|
BUILD_NATIVE can be disabled via menuselect under "Compiler Flags".
|
|
|
|
From 1.8.10 to 1.8.11:
|
|
|
|
* If no transport is specified in sip.conf, transport will default to UDP.
|
|
Also, if multiple transport= lines are used, only the last will be used.
|
|
|
|
From 1.6.2 to 1.8:
|
|
|
|
* chan_sip no longer sets HASH(SIP_CAUSE,<chan name>) on channels by default.
|
|
This must now be enabled by setting 'sipstorecause' to 'yes' in sip.conf.
|
|
This carries a performance penalty.
|
|
|
|
* Asterisk now requires libpri 1.4.11+ for PRI support.
|
|
|
|
* A couple of CLI commands in res_ais were changed back to their original form:
|
|
"ais show clm members" --> "ais clm show members"
|
|
"ais show evt event channels" --> "ais evt show event channels"
|
|
|
|
* The default value for 'autofill' and 'shared_lastcall' in queues.conf has
|
|
been changed to 'yes'.
|
|
|
|
* The default value for the alwaysauthreject option in sip.conf has been changed
|
|
from "no" to "yes".
|
|
|
|
* The behavior of the 'parkedcallstimeout' has changed slightly. The formulation
|
|
of the extension name that a timed out parked call is delivered to when this
|
|
option is set to 'no' was modified such that instead of converting '/' to '0',
|
|
the '/' is converted to an underscore '_'. See the updated documentation in
|
|
features.conf.sample for more information on the behavior of the
|
|
'parkedcallstimeout' option.
|
|
|
|
* Asterisk-addons no longer exists as an independent package. Those modules
|
|
now live in the addons directory of the main Asterisk source tree. They
|
|
are not enabled by default. For more information about why modules live in
|
|
addons, see README-addons.txt.
|
|
|
|
* The rarely used 'event_log' and LOG_EVENT channel have been removed; the few
|
|
users of this channel in the tree have been converted to LOG_NOTICE or removed
|
|
(in cases where the same message was already generated to another channel).
|
|
|
|
* The usage of RTP inside of Asterisk has now become modularized. This means
|
|
the Asterisk RTP stack now exists as a loadable module, res_rtp_asterisk.
|
|
If you are not using autoload=yes in modules.conf you will need to ensure
|
|
it is set to load. If not, then any module which uses RTP (such as chan_sip)
|
|
will not be able to send or receive calls.
|
|
|
|
* The app_dahdiscan.c file has been removed, but the dialplan app DAHDIScan still
|
|
remains. It now exists within app_chanspy.c and retains the exact same
|
|
functionality as before.
|
|
|
|
* The default behavior for Set, AGI, and pbx_realtime has been changed to implement
|
|
1.6 behavior by default, if there is no [compat] section in asterisk.conf. In
|
|
prior versions, the behavior defaulted to 1.4 behavior, to assist in upgrades.
|
|
Specifically, that means that pbx_realtime and res_agi expect you to use commas
|
|
to separate arguments in applications, and Set only takes a single pair of
|
|
a variable name/value. The old 1.4 behavior may still be obtained by setting
|
|
app_set, pbx_realtime, and res_agi each to 1.4 in the [compat] section of
|
|
asterisk.conf.
|
|
|
|
* The PRI channels in chan_dahdi can no longer change the channel name if a
|
|
different B channel is selected during call negotiation. To prevent using
|
|
the channel name to infer what B channel a call is using and to avoid name
|
|
collisions, the channel name format is changed.
|
|
The new channel naming for PRI channels is:
|
|
DAHDI/i<span>/<number>[:<subaddress>]-<sequence-number>
|
|
|
|
* Added CHANNEL(dahdi_span), CHANNEL(dahdi_channel), and CHANNEL(dahdi_type)
|
|
so the dialplan can determine the B channel currently in use by the channel.
|
|
Use CHANNEL(no_media_path) to determine if the channel even has a B channel.
|
|
|
|
* Added AMI event DAHDIChannel to associate a DAHDI channel with an Asterisk
|
|
channel so AMI applications can passively determine the B channel currently
|
|
in use. Calls with "no-media" as the DAHDIChannel do not have an associated
|
|
B channel. No-media calls are either on hold or call-waiting.
|
|
|
|
* The ChanIsAvail application has been changed so the AVAILSTATUS variable
|
|
no longer contains both the device state and cause code. The cause code
|
|
is now available in the AVAILCAUSECODE variable. If existing dialplan logic
|
|
is written to expect AVAILSTATUS to contain the cause code it needs to be
|
|
changed to use AVAILCAUSECODE.
|
|
|
|
* ExternalIVR will now send Z events for invalid or missing files, T events
|
|
now include the interrupted file and bugs in argument parsing have been
|
|
fixed so there may be arguments specified in incorrect ways that were
|
|
working that will no longer work. Please see
|
|
https://wiki.asterisk.org/wiki/display/AST/External+IVR+Interface for details.
|
|
|
|
* OSP lookup application changes following variable names:
|
|
OSPPEERIP to OSPINPEERIP
|
|
OSPTECH to OSPOUTTECH
|
|
OSPDEST to OSPDESTINATION
|
|
OSPCALLING to OSPOUTCALLING
|
|
OSPCALLED to OSPOUTCALLED
|
|
OSPRESULTS to OSPDESTREMAILS
|
|
|
|
* The Manager event 'iax2 show peers' output has been updated. It now has a
|
|
similar output of 'sip show peers'.
|
|
|
|
* VoiceMailMain and VMAuthenticate, if a '*' is entered in the first position
|
|
of a Mailbox or Password, will, if it exists, jump to the 'a' extension in
|
|
the current dialplan context.
|
|
|
|
* The CALLERPRES() dialplan function is deprecated in favor of
|
|
CALLERID(num-pres) and CALLERID(name-pres).
|
|
|
|
* Environment variables that start with "AST_" are reserved to the system and
|
|
may no longer be set from the dialplan.
|
|
|
|
* When a call is redirected inside of a Dial, the app and appdata fields of the
|
|
CDR will now be set to "AppDial" and "(Outgoing Line)" instead of being blank.
|
|
|
|
* The CDR handling of billsec and duration field has changed. If your table
|
|
definition specifies those fields as float,double or similar they will now
|
|
be logged with microsecond accuracy instead of a whole integer.
|
|
|
|
* chan_sip will no longer set up a local call forward when receiving a
|
|
482 Loop Detected response. The dialplan will just continue from where it
|
|
left off.
|
|
|
|
* The 'stunaddr' option has been removed from chan_sip. This feature did not
|
|
behave as expected, had no correct use case, and was not RFC compliant. The
|
|
removal of this feature will hopefully be followed by a correct RFC compliant
|
|
STUN implementation in chan_sip in the future.
|
|
|
|
* The default value for the pedantic option in sip.conf has been changed
|
|
from "no" to "yes".
|
|
|
|
* The ConnectedLineNum and ConnectedLineName headers were added to many AMI
|
|
events/responses if the CallerIDNum/CallerIDName headers were also present.
|
|
The addition of connected line support changes the behavior of the channel
|
|
caller ID somewhat. The channel caller ID value no longer time shares with
|
|
the connected line ID on outgoing call legs. The timing of some AMI
|
|
events/responses output the connected line ID as caller ID. These party ID's
|
|
are now separate.
|
|
|
|
* The Dial application d and H options do not automatically answer the call
|
|
anymore. It broke DTMF attended transfers. Since many SIP and ISDN phones
|
|
cannot send DTMF before a call is connected, you need to answer the call
|
|
leg to those phones before using Dial with these options for them to have
|
|
any effect before the dialed party answers.
|
|
|
|
* The outgoing directory (where .call files are read) now uses inotify to
|
|
detect file changes instead of polling the directory on a regular basis.
|
|
If your outgoing folder is on a NFS mount or another network file system,
|
|
changes to the files will not be detected. You can revert to polling the
|
|
directory by specifying --without-inotify to configure before compiling.
|
|
|
|
* The 'sipusers' realtime table has been removed completely. Use the 'sippeers'
|
|
table with type 'user' for user type objects.
|
|
|
|
* The sip.conf allowoverlap option now accepts 'dtmf' as a value. If you
|
|
are using the early media DTMF overlap dialing method you now need to set
|
|
allowoverlap=dtmf.
|
|
|
|
From 1.6.1 to 1.6.2:
|
|
|
|
* SIP no longer sends the 183 progress message for early media by
|
|
default. Applications requiring early media should use the
|
|
progress() dialplan app to generate the progress message.
|
|
|
|
* The firmware for the IAXy has been removed from Asterisk. It can be
|
|
downloaded from http://downloads.digium.com/pub/iaxy/. To have Asterisk
|
|
install the firmware into its proper location, place the firmware in the
|
|
contrib/firmware/iax/ directory in the Asterisk source tree before running
|
|
"make install".
|
|
|
|
* T.38 FAX error correction mode can no longer be configured in udptl.conf;
|
|
instead, it is configured on a per-peer (or global) basis in sip.conf, with
|
|
the same default as was present in udptl.conf.sample.
|
|
|
|
* T.38 FAX maximum datagram size can no longer be configured in updtl.conf;
|
|
instead, it is either supplied by the application servicing the T.38 channel
|
|
(for a FAX send or receive) or calculated from the bridged endpoint's
|
|
maximum datagram size (for a T.38 FAX passthrough call). In addition, sip.conf
|
|
allows for overriding the value supplied by a remote endpoint, which is useful
|
|
when T.38 connections are made to gateways that supply incorrectly-calculated
|
|
maximum datagram sizes.
|
|
|
|
* There have been some changes to the IAX2 protocol to address the security
|
|
concerns documented in the security advisory AST-2009-006. Please see the
|
|
IAX2 security document, doc/IAX2-security.pdf, for information regarding
|
|
backwards compatibility with versions of Asterisk that do not contain these
|
|
changes to IAX2.
|
|
|
|
* The 'canreinvite' option support by the SIP, MGCP and Skinny channel drivers
|
|
has been renamed to 'directmedia', to better reflect what it actually does.
|
|
In the case of SIP, there are still re-INVITEs issued for T.38 negotiation,
|
|
starting and stopping music-on-hold, and other reasons, and the 'canreinvite'
|
|
option never had any effect on these cases, it only affected the re-INVITEs
|
|
used for direct media path setup. For MGCP and Skinny, the option was poorly
|
|
named because those protocols don't even use INVITE messages at all. For
|
|
backwards compatibility, the old option is still supported in both normal
|
|
and Realtime configuration files, but all of the sample configuration files,
|
|
Realtime/LDAP schemas, and other documentation refer to it using the new name.
|
|
|
|
* The default console now will use colors according to the default background
|
|
color, instead of forcing the background color to black. If you are using a
|
|
light colored background for your console, you may wish to use the option
|
|
flag '-W' to present better color choices for the various messages. However,
|
|
if you'd prefer the old method of forcing colors to white text on a black
|
|
background, the compatibility option -B is provided for this purpose.
|
|
|
|
* SendImage() no longer hangs up the channel on transmission error or on
|
|
any other error; in those cases, a FAILURE status is stored in
|
|
SENDIMAGESTATUS and dialplan execution continues. The possible
|
|
return values stored in SENDIMAGESTATUS are: SUCCESS, FAILURE, and
|
|
UNSUPPORTED. ('OK' has been replaced with 'SUCCESS', and 'NOSUPPORT'
|
|
has been replaced with 'UNSUPPORTED'). This change makes the
|
|
SendImage application more consistent with other applications.
|
|
|
|
* skinny.conf now has separate sections for lines and devices.
|
|
Please have a look at configs/skinny.conf.sample and update
|
|
your skinny.conf.
|
|
|
|
* Queue names previously were treated in a case-sensitive manner,
|
|
meaning that queues with names like "sales" and "sALeS" would be
|
|
seen as unique queues. The parsing logic has changed to use
|
|
case-insensitive comparisons now when originally hashing based on
|
|
queue names, meaning that now the two queues mentioned as examples
|
|
earlier will be seen as having the same name.
|
|
|
|
* The SPRINTF() dialplan function has been moved into its own module,
|
|
func_sprintf, and is no longer included in func_strings. If you use this
|
|
function and do not use 'autoload=yes' in modules.conf, you will need
|
|
to explicitly load func_sprintf for it to be available.
|
|
|
|
* The res_indications module has been removed. Its functionality was important
|
|
enough that most of it has been moved into the Asterisk core.
|
|
Two applications previously provided by res_indications, PlayTones and
|
|
StopPlayTones, have been moved into a new module, app_playtones.
|
|
|
|
* Support for Taiwanese was incorrectly supported with the "tw" language code.
|
|
In reality, the "tw" language code is reserved for the Twi language, native
|
|
to Ghana. If you were previously using the "tw" language code, you should
|
|
switch to using either "zh" (for Mandarin Chinese) or "zh_TW" for Taiwan
|
|
specific localizations. Additionally, "mx" should be changed to "es_MX",
|
|
Georgian was incorrectly specified as "ge" but should be "ka", and Czech is
|
|
"cs", not "cz".
|
|
|
|
* DAHDISendCallreroutingFacility() parameters are now comma-separated,
|
|
instead of the old pipe.
|
|
|
|
* res_jabber: autoprune has been disabled by default, to avoid misconfiguration
|
|
that would end up being interpreted as a bug once Asterisk started removing
|
|
the contacts from a user list.
|
|
|
|
* The cdr.conf file must exist and be configured correctly in order for CDR
|
|
records to be written.
|
|
|
|
* cdr_pgsql now assumes the encoding of strings it is handed are in LATIN9,
|
|
which should cover most uses of the extended ASCII set. If your strings
|
|
use a different encoding in Asterisk, the "encoding" parameter may be set
|
|
to specify the correct character set.
|
|
|
|
From 1.6.0.1 to 1.6.1:
|
|
|
|
* The ast_agi_register_multiple() and ast_agi_unregister_multiple()
|
|
API calls were added in 1.6.0, so that modules that provide multiple
|
|
AGI commands could register/unregister them all with a single
|
|
step. However, these API calls were not implemented properly, and did
|
|
not allow the caller to know whether registration or unregistration
|
|
succeeded or failed. They have been redefined to now return success
|
|
or failure, but this means any code using these functions will need
|
|
be recompiled after upgrading to a version of Asterisk containing
|
|
these changes. In addition, the source code using these functions
|
|
should be reviewed to ensure it can properly react to failure
|
|
of registration or unregistration of its API commands.
|
|
|
|
* The ast_agi_fdprintf() API call has been renamed to ast_agi_send()
|
|
to better match what it really does, and the argument order has been
|
|
changed to be consistent with other API calls that perform similar
|
|
operations.
|
|
|
|
From 1.6.0.x to 1.6.1:
|
|
|
|
* In previous versions of Asterisk, due to the way objects were arranged in
|
|
memory by chan_sip, the order of entries in sip.conf could be adjusted to
|
|
control the behavior of matching against peers and users. The way objects
|
|
are managed has been significantly changed for reasons involving performance
|
|
and stability. A side effect of these changes is that the order of entries
|
|
in sip.conf can no longer be relied upon to control behavior.
|
|
|
|
* The following core commands dealing with dialplan have been deprecated: 'core
|
|
show globals', 'core set global' and 'core set chanvar'. Use the equivalent
|
|
'dialplan show globals', 'dialplan set global' and 'dialplan set chanvar'
|
|
instead.
|
|
|
|
* In the dialplan expression parser, the logical value of spaces
|
|
immediately preceding a standalone 0 previously evaluated to
|
|
true. It now evaluates to false. This has confused a good many
|
|
people in the past (typically because they failed to realize the
|
|
space had any significance). Since this violates the Principle of
|
|
Least Surprise, it has been changed.
|
|
|
|
* While app_directory has always relied on having a voicemail.conf or users.conf file
|
|
correctly set up, it now is dependent on app_voicemail being compiled as well.
|
|
|
|
* SIP: All of the functionality in SIPCHANINFO() has been implemented in CHANNEL(),
|
|
and you should start using that function instead for retrieving information about
|
|
the channel in a technology-agnostic way.
|
|
|
|
* If you have any third party modules which use a config file variable whose
|
|
name ends in a '+', please note that the append capability added to this
|
|
version may now conflict with that variable naming scheme. An easy
|
|
workaround is to ensure that a space occurs between the '+' and the '=',
|
|
to differentiate your variable from the append operator. This potential
|
|
conflict is unlikely, but is documented here to be thorough.
|
|
|
|
* The "Join" event from app_queue now uses the CallerIDNum header instead of
|
|
the CallerID header to indicate the CallerID number.
|
|
|
|
* If you use ODBC storage for voicemail, there is a new field called "flag"
|
|
which should be a char(8) or larger. This field specifies whether or not a
|
|
message has been designated to be "Urgent", "PRIORITY", or not.
|
|
|
