Hi 

I tried to pass the session variable to a restful interface but much of the variable are giving <empty>.  Does anyone know how I can pass channel variable in the curl?  If we can't pass all variables, can we past at least the hangup-cause?  I tried the following and it is giving empty:

 <action application="set" data="api_hangup_hook=curl::http://198.130.149.164:8000/test_takt/Records?callerid=${answer_stamp}&answer_time=${duration}&hangup=${destination_number}&hangup2=${answered_time}&sip=${endpoint_disposition}&state=${state}&originate_disposition=${originate_disposition}&hangup_cause=${hangup_cause}&sip_term_status=${sip_term_status}&proto_specific_hangup_cause=${proto_specific_hangup_cause}&variable_sip_term_status=${variable_sip_term_status}&variable_sip_hangup_disposition=${variable_sip_hangup_disposition}&endpoint_disposition=${endpoint_disposition}&variable_endpoint_disposition=${variable_endpoint_disposition}&sip_hangup_disposition=${sip_hangup_disposition}&answer_stamp=${answer_stamp}&answer_epoch=${answer_epoch}&end=${env}"/>

The other question i have is that I tried to execute two api in the api_hangup_hook, it does not call the second api.  Does anyone know how to do this or is it possible to do?

<action application="set" data="api_hangup_hook=curl::http://198.100.149.164:8000/test_takt/Records?callerid=${caller_id} curl::http://198.100.149.164:8000/test_takt/Records?callerid=${destination_number}"/>
