I'm using sip.js with FS (tried FS 1.5.15 and 1.7). Upgrading to Firefox 39 is seems to be bad idea, cause call through it fails due to
2015-07-15 10:48:39.168250 [ERR] switch_rtp.c:2907 audio Handshake failure 1
2015-07-15 10:48:39.168250 [INFO] switch_rtp.c:2908 Changing audio DTLS state from HANDSHAKE to FAIL
On FF 38 and Chrome all is ok.
Am I only one with this issue of it's really something wrong with FF?
