Define a callgroup for internal extensions
Most incoming calls are expected to go to all extensions. Therefore we need to configure a call group to handle this. This is done by configuring a special extension and then using this to dial the others.
Define the extension number so we can use that elsewhere
I did this in vars.xml. So add an entry like:
<!-- replace xxx with the "common" extension number --> <X-PRE-PROCESS cmd="set" data="DEFAULT_EXTENSION=xxx"/>
For each extension you want included in directory/default/xxx.xml add in the variables section a mention to the call group
<include>
<user id="xxx">
<params>
...
</params>
<variables>
...
<variable name="callgroup" value="internal_users"/>
</variables>
</user>
</include>
In dialplan/default.xml add the new call group
<extension name="group_dial_internal_users">
<condition field="destination_number" expression="^$${DEFAULT_EXTENSION}$">
<action application="bridge" data="group/internal_users@${domain_name}"/>
</condition>
</extension>
Cleanup default call groups
If you don’t need the default FreeSWITCH groups group_dial_sales, group_dial_support, group_dial_billing
then these can be removed in dialplan/default.xml and directory/default.xml where these groups are defined.
