Tried this

<extension name="balance_load">

      <condition regex="any" break="never">

                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"  inline="true"/>

                <regex field="current_node" expression="^1"/>

                <action application="set" data="current_node=2" inline="true"/>

                <anti-action application="set" data="current_node=1" inline="true"/>

                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"  inline="true"/>

      </condition>

      <condition field="destination_number" expression="^5050$">

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

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

                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"  inline="true"/>

                <regex field="current_node" expression="^1"/>

                <action application="bridge" data="loopback/5000"/>

                <anti-action application="bridge" data="sofia/external/5000@172.18.19.72"/>

      </condition>

Did not work either. No matter what is the value for current_node, always executes "anti-action".

try not nesting your conditions and stack them instead.

Thanks for the reply. I changed dialplan as following and still same results

                <action application="bridge" data="loopback/5000"/>

      </condition>

    </extension>

Interestingly this is what I see in Freeswitch traces

2016-03-23 11:07:22.895579 [INFO] mod_dptools.c:1692 *********LOG LEVEL******** [1]

2016-03-23 11:07:22.895579 [INFO] mod_dptools.c:1692 *********LOG LEVEL AFTER******** [1]

2016-03-23 11:07:22.895579 [INFO] mod_loopback.c:1075 Sending early media

Even if value for "current_node" is 1 it does not go to <condition field="${current_node}" expression="^1$"> condition. At least it should go there.

As with any variables (channel or global) variables are expanded when the dialplan is processed, then a list of actions is built, based on conditions that are met. This is called the Routing Stage in FreeSWITCH Call Processing.

One that Routing Stage is completed, then we move to the Execute Stage where the Actions (or anti-actions) that were added to the list of things to do are executed.

In your example the vars are expanded before the set and log application actions are actually executed.

See https://freeswitch.org/confluence/display/FREESWITCH/XML+Dialplan and look for inline=”true” for a more complete explanation on way to do what you are trying.

Subject: [Freeswitch-users] Need to set and get Global vairables from dialplan

Hi,

I have created a variable in var.xml, current_node. I am trying to use it in dialplan as below, is this something I can do?

<extension name="balance_load">

      <condition field="destination_number" expression="^5050$">

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

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

                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"/>

                <condition field="current_node" expression="^1$">

                                <action="set_global" data="current_node=2"/>

                                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"/>

                                <action application="bridge" data="loopback/5000"/>

                </condition>

                <condition field="current_node" expression="^2$">

                                <action="set_global" data="current_node=2"/>

                                <action application="log" data="INFO *********LOG LEVEL******** [${current_node}]"/>

                                <action application="bridge" data="sofia/external/5000@172.18.19.72"/>

                </condition>

                <action="set_global" data="current_node=2"/>

                <action application="log" data="INFO *********LOG LEVEL AFTER******** [${current_node}]"/>

                <action application="bridge" data="loopback/5000"/>

      </condition>

    </extension>

Currently log always print current_node = 1 which is the value set in vars.xml.

Thanks,

Varsha
