Example AMI Redirect command to answer ringing call on 202. Caller=203: ----------------------------------------------------------------------- Action: Redirect Channel: SIP/203-09f7e4f0 Context: CTI_AUTO_ANSWER Exten: 202 Priority: 1 ActionID: 8-srv06D1FFAF Variable: SIPADDHEADER01=Call-Info: \;answer-after=0 The Asterisk has to process this action and should in result send a new INVITE to extension 202 with auto-answer header. And the telephone/softphone must have enabled the feature "auto-answer by call-info". You have to search in your telephone/softphone configuration to find this feature. Mabe, the feature does not exist at all.
