[Freeswitch-users] limit app problem with loopback channels

[Michael Collins]

You can solve this issue by avoiding loopback. Don't use loopback unless
there is absolutely no other alternative. Try replacing the loopback calls
in the group definition to "user/xxx" instead:

   <extension name="group_dial_sales">
     <condition field="destination_number" expression="^2000$">
       <action application="bridge"
data="[execute_on_answer='limit hash callwaiting 1000 1']user/1000,
[execute_on_answer='limit hash callwaiting
1001 1']user/1001"/>
     </condition>
   </extension>

This is just off the top of my head, so please do the usual testing and
tinkering before you report back that it does not work. :)
