[Freeswitch-users] call ivr from android + chrome with no audio

i've set my fs server for webrtc test and looks everything is fine until i was to test an ivr call from android + chrome, fs console can respond to the sip call process but after the call is answered, there's no DTLS handshake message as there's with pc + chrome: [INFO] switch_rtp.c:2449 Changing audio DTLS state from HANDSHAKE to SETUP [INFO] switch_rtp.c:2368 audio Fingerprint Verified. [INFO] switch_rtp.c:2868 Activating Audio Secure RTP SEND [INFO] switch_rtp.c:2846 Activating Audio Secure RTP RECV however call to webrtc.freeswitch.org is fine, what makes the diference between the 2 fs sets?
