[Freeswitch-users] Check user state in dialplan

Hi, I need to perform different actions in response to the following conditions: * The called number is not exists in the directory (check id and number-alias) * The called number is known, but not registered * The called number is busy * The called number is not answered due timeout * The called number is answered In the first case I need to send the call through a particular gateway, in the next two cases I need to play a file, in two remaining cases I need to call user and play a file only on timeout. What is the right to do it in the dialplan? -- Regards, Eugene Prokopiev
