[Freeswitch-users] please help!!! how to limit each FS registered user's active calls

[Steven Ayre]

"limit subsystem hash not found!" means you have not loaded mod_hash

As for changing the limit line from $1 to 11 what you've done is any
calls to other numbers such as 05 are also registered as a call to 11.
Therefore a call to 05 will prevent a call to 11.

If you want to handle 11 differently from the others, you'll need to
put it in a different extension:

<extension name="PBX Extension 11">
    <condition field="destination_number" expression="^(11)$">
        <action application="limit" data="db ${domain} $1 1
handle_over_limit XML over_limit_actions"/>
        <action application="bridge" data="user/$1"/>
    </condition>
</extension>
<extension name="PBX Extension">
    <condition field="destination_number" expression="^(1[0-9]{1})$">
        <action application="bridge" data="user/$1"/>
    </condition>
</extension>
