3 === Information for upgrading between Asterisk 1.6 versions
5 === These files document all the changes that MUST be taken
6 === into account when upgrading between the Asterisk
7 === versions listed below. These changes may require that
8 === you modify your configuration files, dialplan or (in
9 === some cases) source code if you have your own Asterisk
10 === modules or patches. These files also includes advance
11 === notice of any functionality that has been marked as
12 === 'deprecated' and may be removed in a future release,
13 === along with the suggested replacement functionality.
15 === UPGRADE-1.2.txt -- Upgrade info for 1.0 to 1.2
16 === UPGRADE-1.4.txt -- Upgrade info for 1.2 to 1.4
17 === UPGRADE-1.6.txt -- Upgrade info for 1.4 to 1.6
19 ===========================================================
23 * Asterisk-addons no longer exists as an independent package. Those modules
24 now live in the addons directory of the main Asterisk source tree. They
25 are not enabled by default. For more information about why modules live in
26 addons, see README-addons.txt.
28 * The rarely used 'event_log' and LOG_EVENT channel have been removed; the few
29 users of this channel in the tree have been converted to LOG_NOTICE or removed
30 (in cases where the same message was already generated to another channel).
32 * The usage of RTP inside of Asterisk has now become modularized. This means
33 the Asterisk RTP stack now exists as a loadable module, res_rtp_asterisk.
34 If you are not using autoload=yes in modules.conf you will need to ensure
35 it is set to load. If not, then any module which uses RTP (such as chan_sip)
36 will not be able to send or receive calls.
38 * The app_dahdiscan.c file has been removed, but the dialplan app DAHDIScan still
39 remains. It now exists within app_chanspy.c and retains the exact same
40 functionality as before.
42 * The default behavior for Set, AGI, and pbx_realtime has been changed to implement
43 1.6 behavior by default, if there is no [compat] section in asterisk.conf. In
44 prior versions, the behavior defaulted to 1.4 behavior, to assist in upgrades.
45 Specifically, that means that pbx_realtime and res_agi expect you to use commas
46 to separate arguments in applications, and Set only takes a single pair of
47 a variable name/value. The old 1.4 behavior may still be obtained by setting
48 app_set, pbx_realtime, and res_agi each to 1.4 in the [compat] section of
51 * The PRI channels in chan_dahdi can no longer change the channel name if a
52 different B channel is selected during call negotiation. To prevent using
53 the channel name to infer what B channel a call is using and to avoid name
54 collisions, the channel name format is changed.
55 The new channel naming for PRI channels is:
56 DAHDI/ISDN-<span>-<sequence-number>
60 * The firmware for the IAXy has been removed from Asterisk. It can be
61 downloaded from http://downloads.digium.com/pub/iaxy/. To have Asterisk
62 install the firmware into its proper location, place the firmware in the
63 contrib/firmware/iax/ directory in the Asterisk source tree before running
66 * T.38 FAX error correction mode can no longer be configured in udptl.conf;
67 instead, it is configured on a per-peer (or global) basis in sip.conf, with
68 the same default as was present in udptl.conf.sample.
70 * There have been some changes to the IAX2 protocol to address the security
71 concerns documented in the security advisory AST-2009-006. Please see the
72 IAX2 security document, doc/IAX2-security.pdf, for information regarding
73 backwards compatibility with versions of Asterisk that do not contain these
76 * The 'canreinvite' option support by the SIP, MGCP and Skinny channel drivers
77 has been renamed to 'directmedia', to better reflect what it actually does.
78 In the case of SIP, there are still re-INVITEs issued for T.38 negotiation,
79 starting and stopping music-on-hold, and other reasons, and the 'canreinvite'
80 option never had any effect on these cases, it only affected the re-INVITEs
81 used for direct media path setup. For MGCP and Skinny, the option was poorly
82 named because those protocols don't even use INVITE messages at all. For
83 backwards compatibility, the old option is still supported in both normal
84 and Realtime configuration files, but all of the sample configuration files,
85 Realtime/LDAP schemas, and other documentation refer to it using the new name.
87 * The default console now will use colors according to the default background
88 color, instead of forcing the background color to black. If you are using a
89 light colored background for your console, you may wish to use the option
90 flag '-W' to present better color choices for the various messages. However,
91 if you'd prefer the old method of forcing colors to white text on a black
92 background, the compatibility option -B is provided for this purpose.
94 * SendImage() no longer hangs up the channel on transmission error or on
95 any other error; in those cases, a FAILURE status is stored in
96 SENDIMAGESTATUS and dialplan execution continues. The possible
97 return values stored in SENDIMAGESTATUS are: SUCCESS, FAILURE, and
98 UNSUPPORTED. ('OK' has been replaced with 'SUCCESS', and 'NOSUPPORT'
99 has been replaced with 'UNSUPPORTED'). This change makes the
100 SendImage application more consistent with other applications.
102 * skinny.conf now has separate sections for lines and devices.
103 Please have a look at configs/skinny.conf.sample and update
106 * Queue names previously were treated in a case-sensitive manner,
107 meaning that queues with names like "sales" and "sALeS" would be
108 seen as unique queues. The parsing logic has changed to use
109 case-insensitive comparisons now when originally hashing based on
110 queue names, meaning that now the two queues mentioned as examples
111 earlier will be seen as having the same name.
113 * The SPRINTF() dialplan function has been moved into its own module,
114 func_sprintf, and is no longer included in func_strings. If you use this
115 function and do not use 'autoload=yes' in modules.conf, you will need
116 to explicitly load func_sprintf for it to be available.
118 * The res_indications module has been removed. Its functionality was important
119 enough that most of it has been moved into the Asterisk core.
120 Two applications previously provided by res_indications, PlayTones and
121 StopPlayTones, have been moved into a new module, app_playtones.
123 * Support for Taiwanese was incorrectly supported with the "tw" language code.
124 In reality, the "tw" language code is reserved for the Twi language, native
125 to Ghana. If you were previously using the "tw" language code, you should
126 switch to using either "zh" (for Mandarin Chinese) or "zh_TW" for Taiwan
127 specific localizations. Additionally, "mx" should be changed to "es_MX",
128 Georgian was incorrectly specified as "ge" but should be "ka", and Czech is
131 From 1.6.0.1 to 1.6.1:
133 * The ast_agi_register_multiple() and ast_agi_unregister_multiple()
134 API calls were added in 1.6.0, so that modules that provide multiple
135 AGI commands could register/unregister them all with a single
136 step. However, these API calls were not implemented properly, and did
137 not allow the caller to know whether registration or unregistration
138 succeeded or failed. They have been redefined to now return success
139 or failure, but this means any code using these functions will need
140 be recompiled after upgrading to a version of Asterisk containing
141 these changes. In addition, the source code using these functions
142 should be reviewed to ensure it can properly react to failure
143 of registration or unregistration of its API commands.
145 * The ast_agi_fdprintf() API call has been renamed to ast_agi_send()
146 to better match what it really does, and the argument order has been
147 changed to be consistent with other API calls that perform similar
150 From 1.6.0.x to 1.6.1:
152 * In previous versions of Asterisk, due to the way objects were arranged in
153 memory by chan_sip, the order of entries in sip.conf could be adjusted to
154 control the behavior of matching against peers and users. The way objects
155 are managed has been significantly changed for reasons involving performance
156 and stability. A side effect of these changes is that the order of entries
157 in sip.conf can no longer be relied upon to control behavior.
159 * The following core commands dealing with dialplan have been deprecated: 'core
160 show globals', 'core set global' and 'core set chanvar'. Use the equivalent
161 'dialplan show globals', 'dialplan set global' and 'dialplan set chanvar'
164 * In the dialplan expression parser, the logical value of spaces
165 immediately preceding a standalone 0 previously evaluated to
166 true. It now evaluates to false. This has confused a good many
167 people in the past (typically because they failed to realize the
168 space had any significance). Since this violates the Principle of
169 Least Surprise, it has been changed.
171 * While app_directory has always relied on having a voicemail.conf or users.conf file
172 correctly set up, it now is dependent on app_voicemail being compiled as well.
174 * SIP: All of the functionality in SIPCHANINFO() has been implemented in CHANNEL(),
175 and you should start using that function instead for retrieving information about
176 the channel in a technology-agnostic way.
178 * If you have any third party modules which use a config file variable whose
179 name ends in a '+', please note that the append capability added to this
180 version may now conflict with that variable naming scheme. An easy
181 workaround is to ensure that a space occurs between the '+' and the '=',
182 to differentiate your variable from the append operator. This potential
183 conflict is unlikely, but is documented here to be thorough.
185 * The "Join" event from app_queue now uses the CallerIDNum header instead of
186 the CallerID header to indicate the CallerID number.
188 * If you use ODBC storage for voicemail, there is a new field called "flag"
189 which should be a char(8) or larger. This field specifies whether or not a
190 message has been designated to be "Urgent", "PRIORITY", or not.
