I have tried to access the variables shown by the application info, and the variable name to be used is generally not the same as the name listed by info. I have listed nearly 100 variables below, where I guessed the "real" names, but a number are still missing, and I would like to know what the "real" names are or how I derive the right names. Some of the problem-variables, though, for instance Channel-Read-Codec-Name are also found further down in the list as variable_read_codec, which can be read alright, and the presence of two variable names which may have the same value seems confusing for a dummy as me. The info-names have been taken - as an example - from the info result of a call that has been diverted by the phone. The list below shows my guess (via a javascript), and when the third column shows FALSE, the guess need to be corrected. In some cases, the reason for the "FALSE" may be related to the fact that the variable is unassigned: Info-name---Guessed name---Result Channel-State---Channel_State---FALSE Channel-State-Number---Channel_State_Number---FALSE Channel-Name---Channel_Name---OK Unique-ID---Unique_ID---FALSE Call-Direction---Call_Direction---FALSE Answer-State---Answer_State---FALSE Channel-Read-Codec-Name---Channel_Read_Codec_Name---FALSE Channel-Read-Codec-Rate---Channel_Read_Codec_Rate---FALSE Channel-Write-Codec-Name---Channel_Write_Codec_Name---FALSE Channel-Write-Codec-Rate---Channel_Write_Codec_Rate---FALSE Caller-Username---Username---OK Caller-Dialplan---Dialplan---OK Caller-Caller-ID-Name---Caller_ID_Name---OK Caller-Caller-ID-Number---Caller_ID_Number---OK Caller-Network-Addr---Network_Addr---OK Caller-Destination-Number---Destination_Number---OK Caller-Unique-ID---Unique_ID---FALSE Caller-Source---Source---OK Caller-Context---Context---OK Caller-RDNIS---RDNIS---OK Caller-Channel-Name---Channel_Name---OK Caller-Profile-Index---Profile_Index---OK Caller-Channel-Created-Time---Channel_Created_Time---FALSE Caller-Channel-Answered-Time---Channel_Answered_Time---FALSE Caller-Channel-Hangup-Time---Channel_Hangup_Time---FALSE Caller-Channel-Transfer-Time---Channel_Transfer_Time---FALSE Caller-Screen-Bit---Screen_Bit---FALSE Caller-Privacy-Hide-Name---Privacy_Hide_Name---FALSE Caller-Privacy-Hide-Number---Privacy_Hide_Number---FALSE variable_sip_received_ip---sip_received_ip---OK variable_sip_received_port---sip_received_port---OK variable_sip_authorized---sip_authorized---OK variable_sip_mailbox---sip_mailbox---OK variable_sip_auth_username---sip_auth_username---OK variable_sip_auth_realm---sip_auth_realm---OK variable_mailbox---mailbox---OK variable_user_name---user_name---OK variable_domain_name---domain_name---OK variable_record_stereo---record_stereo---OK variable_accountcode---accountcode---OK variable_user_context---user_context---OK variable_effective_caller_id_name---effective_caller_id_name---OK variable_effective_caller_id_number---effective_caller_id_number---OK variable_caller_domain---caller_domain---OK variable_sip_from_user---sip_from_user---OK variable_sip_from_uri---sip_from_uri---OK variable_sip_from_host---sip_from_host---OK variable_sip_from_user_stripped---sip_from_user_stripped---OK variable_sip_from_tag---sip_from_tag---OK variable_sofia_profile_name---sofia_profile_name---OK variable_sofia_profile_domain_name---sofia_profile_domain_name---OK variable_sip_req_params---sip_req_params---OK variable_sip_req_user---sip_req_user---OK variable_sip_req_uri---sip_req_uri---OK variable_sip_req_host---sip_req_host---OK variable_sip_to_params---sip_to_params---OK variable_sip_to_user---sip_to_user---OK variable_sip_to_uri---sip_to_uri---OK variable_sip_to_host---sip_to_host---OK variable_sip_contact_params---sip_contact_params---OK variable_sip_contact_user---sip_contact_user---OK variable_sip_contact_port---sip_contact_port---OK variable_sip_contact_uri---sip_contact_uri---OK variable_sip_contact_host---sip_contact_host---OK variable_channel_name---channel_name---OK variable_sip_call_id---sip_call_id---OK variable_sip_user_agent---sip_user_agent---OK variable_sip_via_host---sip_via_host---OK variable_sip_via_port---sip_via_port---OK variable_sip_via_rport---sip_via_rport---OK variable_presence_id---presence_id---OK variable_sip_h_P-Key-Flags---sip_h_P_Key_Flags---FALSE variable_switch_r_sdp---switch_r_sdp---OK variable_remote_media_ip---remote_media_ip---OK variable_remote_media_port---remote_media_port---OK variable_write_codec---write_codec---OK variable_write_rate---write_rate---OK variable_endpoint_disposition---endpoint_disposition---OK variable_dialed_ext---dialed_ext---OK variable_transfer_ringback---transfer_ringback---OK variable_call_timeout---call_timeout---OK variable_hangup_after_bridge---hangup_after_bridge---OK variable_continue_on_fail---continue_on_fail---OK variable_dialed_user---dialed_user---OK variable_dialed_domain---dialed_domain---OK variable_sip_redirect_contact_user_0---sip_redirect_contact_user_0---OK variable_sip_redirect_contact_host_0---sip_redirect_contact_host_0---OK variable_sip_h_Referred-By---sip_h_Referred_By---FALSE variable_sip_refer_to---sip_refer_to---OK variable_max_forwards---max_forwards---OK variable_originate_disposition---originate_disposition---OK variable_read_codec---read_codec---OK variable_read_rate---read_rate---OK variable_open---open---OK variable_use_profile---use_profile---OK variable_current_application---current_application---OK
