[Freeswitch-users] Starting dtmf_generation with mod_lcr

Hello. I use lcr for outbound connection to providers based on phone call price. On one provider I need to use start_dtmf_generate to force recoding sip info from local extensions to inband dtmf. Setting variable from lcr execute_on_answer=start_dtmf_generate does not work. Also gateway profile have <variables> <variable direction="outbound" name="dtmf_type" value="none"/> </variables> <param name="dtmf-type" value="none"/> this also does not help. How can I accomplish per provider dtmf_generate for outbound calls?
