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

[ran zhang]

Mike:

     I have added 'limits.xml' as u said.   If i use 'hash', FS 
generates error "limit subsystem hash not found!", so i changed to 'db', 
following is my local extension in my dialplan, i changed '$1' to '11' 
since i just want to limit user/11, but its still limiting incoming 
calls on all the extensions.


    Also, is creating 'limits.xml' required?

    Would it work if i can just add 'handle_over_limit' extension in 
'default.xml', omit the 'XML over_limit_actions' part in the limit action?




<extension name="PBX Extension">
<condition field="destination_number" expression="^(1[0-9]{1})$">

<action application="limit" data="db ${domain} 11 1 handle_over_limit 
XML over_limit_actions"/>
<action application="bridge" data="user/$1"/>

</condition>
</extension>
