Good morning, I defined in my directory (/usr/local/freeswitch/conf/directory) a variable called accountcode (it's okey if it has to be another name because this is already in use) with value 7777. What I need is that in the dialplan is set as a variable so that i can use it as a SIP_Header for my call as sip-h-P-Charge-Info, like follows: <extension name="saliente"> <condition field="destination_number" expression="^(\d+)$" break="on-true"> <action application="set" data="effective_caller_id_number=${caller_id_number}"/> <action application="set"><![CDATA[sip_h_P-Charge-Info=${accountcode}]]></action> <action application="bridge" data="sofia/gateway/NP/$1"/> </condition> </extension> Is it that posible? How can I solve it? Thank you in advance
