[Freeswitch-users] Unbridge inbound and outbound legs

Good day to everyone! Could you please advise me how to unbridge inbound and outbound legs via ESL? Basically, what I need is on certain dtmf on outbound leg, "unbridge" inbound and outbound legs and put inbound call on music_on_hold. Both legs should not affect each other after "unbridge" Please advise me how to do it, I am lost :( Thank you for advise, Best regards Nikolay
