Hi, If i create a conference via dialplan tool 'conference' like <action application="conference_set_auto_outcall" data="{sip_auto_answer=false}sofia/internal/220"/> ... <anti-action application="conference" data="555@default <mailto:555@default> 555 TestConf"/> , ... the caller_caller_id_name and caller_caller_id_number in the CHANNEL_CALLSTATE Event for Event calling function 'switch_channel_perform_set_callstate' for the OUTBOUND Channel state 'RINGING' was set to 'FreeSWITCH' and '00000000' I cannot set these variables to another value. No set of channel variables via dialplan tools 'set' or via dialstring variables like '{outbound_caller_id=555}555@default 555 TestConf' or with other variables. How can i set these variables to another value by the dialplan or conference configuration dynamicaly? How can i not ? Gernerally, How can i push more informations to these Event function? Thanks David
