But when i try using dialtype 'RATIO', i am facing issue when freeswitch is resending the provider(gateway)'s response to vicidial the asterisk of vicidial server responding with X-Asterisk-HangupCause: Unknown. X-Asterisk-HangupCauseCode: 0. I am attaching the sip log of both working(MANUAL) and and not working(RATIO) scenario here.
