[Freeswitch-users] Conditions

Wed Jun 13 16:39:47 MSD 2012

I was about to answer and say  <action> tags must be inside <condition> tags.

I think you can in fact remove you break=”never” everywhere except:

                       <condition field="${testvarA}" expression="^$" break="never" />

Your first “condition” can just be “<condition>”  which is always true.

And  <condition field="${testvarB}" expression="^$" break="never"> 

doesn’t need a break=”never” as it has <action> and <anti-action>s.

Hope that helps (and is correct!)

OK... I think there's a fundamental misunderstanding about what code actually gets executed.

The setting never happened in my example. If I change it to:

        <condition field="${ani}" expression="^(\d+)$" break="never" >
        <action inline="true" application="set" data="testvarA=hello"/>
        <action inline="true" application="set" data="testvarB=hello"/>
        </condition>
       <condition field="${testvarA}" expression="^$" break="never" />
        <condition field="${testvarB}" expression="^$" break="never">
                <action application="log" data="WARNING TestVarsA and B are both empty"/>
                <anti-action application="log" data="WARNING TestVarsA and B are NOT both empty"/>
       </condition>

Then it works. (Comparing ani to any number of digits).
What I really want is something like <condition expression="true">

Mmm. Strangely enough, I stumbled on that just after posting, but it still doesn't work

        <action inline="true" application="set" data="testvarA=hello"/>
        <action inline="true" application="set" data="testvarB=hello"/>
       <condition field="${testvarA}" expression="^$" />
        <condition field="${testvarB}" expression="^$" >
                <action application="log" data="WARNING TestVarsA and B are both empty"/>
                <anti-action application="log" data="WARNING TestVarsA and B are NOT both empty"/>
       </condition>

Result: "TestVarsA and B are both empty"

hello alex, 

you must set testvarA and testvarB as inline

check this  http://wiki.freeswitch.org/wiki/Dialplan_XML#Inline_Actions

I've been struggling a bit with conditions. In particular the "break"
attribute, which I couldn't really find any documentation on.

<action application="set" data="testvarA=hello/>
<action application="set" data="testvarB=hello/>
<condition field="${testvarA}" expression="^$" />
<condition field="${testvarB}" expression="^$" >
   <action application="log" data="WARNING TestVarsA and B are both
empty"/>
   <anti-action application="log" data="WARNING TestVarsA and B are NOT
both empty"/>
</condition>

The above gives "TestVarsA and B are both empty" which I don't understand!

I think it would be nice to put some examples in the wiki that translate
from the usual way of doing things (perhaps using PHP or JavaScript
notation) to the dialplan format.

For example, I have a requirement that might be expressed like this:

<context name="dp0095">
<extension name="Outbound_call">
    if (${default_ani_prefix} == "" and sip_auth_username == "") {
<action application="log" data="WARNING default_ani_prefix and
sip_auth_username are not set (A)"/>
<action application="set" data="default_ani_prefix=${tenant_id}${b_ext}1"/>
    }
    if (${default_ani_prefix} == "") {
<action application="log" data="WARNING default_ani_prefix is not set (B)"/>
<action application="set" data="ani_prefix=${sip_auth_username}0"/>
    } else {
<action application="set" data="ani_prefix=${default_ani_prefix}"/>
    }
    if ($destination_number == "^(\d{8}.*)") {
<action application="bridge"
data="[tenant_id=${tenant_id},a_ext=${a_ext},b_ext=${b_ext},origination_callee_id_number=$1,origination_caller_id_number=${ani_prefix}${ani}]sofia/internal/8980000000002$1 at 193.105.54.10"/>
    }
</extension>
</context>

What is the nefarious combination of conditions, breaks, actions and
anti-actions required to implement this?

I'm happy to try and put a newbie-perspective updates into some part of
the wiki. Talking of which, maybe it would be good to have more
example-based content in the wiki, but put it in a separate section so
that it doesn't clutter up the more reference-orientated bits.
