The 'set' application sets the variable on the a-leg, while the {} sets the variable on the b-leg. When the b-leg call is being placed it only checks its own copy of the variable.

Use 'export' instead of 'set' and you'll get the behaviour you're expecting.

Hi there,

I am testing carrier failover via the dialplan. 

Can anyone tell why me the following two dial plans act differently? In my mind they are the same so I am flummoxed.

 

<extension name="treatment_followme_route">

     <condition field="${Treatment}" expression="^SEQUENTIAL$"/>

<condition field="${ForwardingNumber}" expression="^100">

<action application="set" data="ignore_early_media=true"/>

<action application="set" data="continue_on_fail=true"/>

<action application="set" data="call_timeout=5"/> 

<action application="bridge" data="user/1001|user/1001"/>

<action application="set" data="call_timeout=20"/> 

<action application="bridge" data="user/1002|user/1002"/> 

...

      </condition>

</extension>

VERUS:

<extension name="treatment_followme_route">

     <condition field="${Treatment}" expression="^SEQUENTIAL$"/>

<condition field="${ForwardingNumber}" expression="^100">

<action application="set" data="ignore_early_media=true"/>

<action application="set" data="continue_on_fail=true"/>

<action application="bridge" data="{call_timeout=5}user/1001|user/1001"/>

<action application="bridge" data="{call_timeout=20}user/1002|user/1002"/> 

..

      </condition>

    </extension>

First dial plan will dial user 1001 once followed by 1002 once - which is correct for my purposes

Second will dial user 1001 twice followed by 1002 twice

Why would {call_timeout=15} change the nature of that bridge and <action application="set" data="call_timeout=5"/> not?

Thanks

Phil
