Git does not support the ability to replace a token with a version string during check-in. While it does have support for replacing a token on clone, this is somewhat sub-optimal: the token is replaced with the object hash, which is not particularly easy for human consumption. What's more, in practice, the source file version was often not terribly useful. Generally, when triaging bugs, the overall version of Asterisk is far more useful than an individual SVN version of a file. As a result, this patch removes Asterisk's support for showing source file versions. Specifically, it does the following: * Rename ASTERISK_FILE_VERSION macro to ASTERISK_REGISTER_FILE, and remove passing the version in with the macro. Other facilities than 'core show file version' make use of the file names, such as setting a debug level only on a specific file. As such, the act of registering source files with the Asterisk core still has use. The macro rename now reflects the new macro purpose. * main/asterisk: - Refactor the file_version structure to reflect that it no longer tracks a version field. - Remove the "core show file version" CLI command. Without the file version, it is no longer useful. - Remove the ast_file_version_find function. The file version is no longer tracked. - Rename ast_register_file_version/ast_unregister_file_version to ast_register_file/ast_unregister_file, respectively. * main/manager: Remove value from the Version key of the ModuleCheck Action. The actual key itself has not been removed, as doing so would absolutely constitute a backwards incompatible change. However, since the file version is no longer tracked, there is no need to attempt to include it in the Version key. * UPGRADE: Add notes for: - Modification to the ModuleCheck AMI Action - Removal of the "core show file version" CLI command Change-Id: I6cf0ff280e1668bf4957dc21f32a5ff43444a40e

Manages a group of users for dialing.

<parameter name="op">
|
|
<para>The operation name, possible values are:</para>
|
|
<para><literal>add</literal> - add a channel name or interface (write-only)</para>

<para><literal>del</literal> - remove a channel name or interface (write-only)</para>

<description>
|
|
<para>Presents an interface meant to be used in concert with the Dial
|
|
application, by presenting a list of channels which should be dialled when
|
|
referenced.</para>
|
|
<para>When DIALGROUP is read from, the argument is interpreted as the particular
|
|
<replaceable>group</replaceable> for which a dial should be attempted. When DIALGROUP is written to
|
|
with no arguments, the entire list is replaced with the argument specified.</para>
|
|
<para>Functionality is similar to a queue, except that when no interfaces are
|
|
available, execution may continue in the dialplan. This is useful when
|
|
you want certain people to be the first to answer any calls, with immediate
|
|
fallback to a queue when the front line people are busy or unavailable, but
|
|
you still want front line people to log in and out of that group, just like
|
|
a queue.</para>
|
|
<para>Example:</para>
|
|
<para>exten => 1,1,Set(DIALGROUP(mygroup,add)=SIP/10)</para>
|
|
<para>exten => 1,n,Set(DIALGROUP(mygroup,add)=SIP/20)</para>
|
|
<para>exten => 1,n,Dial(${DIALGROUP(mygroup)})</para>
