[Freeswitch-users] Time of day routing / too many stacked extensions

[Steven Ayre]

You have recursion.

expression is a regular expression. You need ^ and $ to match the start and
end of the string, without them it'll match the expression appearing
anywhere in the string. As a result...

    <extension name="DDI_9600" continue="true">
      <condition field="destination_number" expression="441614249600">
        <action application="execute_extension"
data="441614249600_${office_status}"/>
      </condition>
    </extension>

This executes itself again and again and again... it never reaches the next
extension.

These conditions would avoid the issue:
      <condition field="destination_number" expression="^441614249600$">
      <condition field="destination_number"
expression="^441614249600_open$">
      <condition field="destination_number"
expression="^441614249600_closed$">

As an alternative implementation you could also do this in a single
extension:
   <extension name="DDI_9600">
      <condition field="destination_number" expression="^441614249600$"/>
      <condition field="${office_status}" expression="^open$">
       <!-- open -->
       <action application="set" data="domain_name=$${domain}"/>
       <action application="set"
data="effective_caller_id_name=${cidlookup(${caller_id_number})}"/>
       <action application="ivr" data="bashton_9600_open"/>
       <!-- closed -->
       <anti-action application="set" data="domain_name=$${domain}"/>
       <anti-action application="set"
data="effective_caller_id_name=${cidlookup(${caller_id_number})}"/>
       <anti-action application="ivr" data="bashton_9600_closed"/>
      </condition>
    </extension>

Note this only works because you're setting inline="true" when setting
${office_status}.
