Hi,
We are having trouble getting WebRTC working with 1.6. I have tracked the problem down to the do_dtls function in switch_rtp.c (shown partially below). Two things we have noticed:
1) It appears that ice.ready and ice.ready are always 0.
2) DTLS negotiation never completes the handshake.
Does ice have to be operative in order for dtls negotiation to proceed or the other way around? What should I look for, which may prevent the ice setup and/or dtls handshake.
We are running on google cloud. Are there networking/NAT issues running on cloud servers that might interfere with either ICE or DTLS?
Thanks in advance.

static int do_dtls(switch_rtp_t *rtp_session, switch_dtls_t *dtls)
{
int r = 0, ret = 0, len;
switch_size_t bytes;
unsigned char buf[4096] = "";
int ready = rtp_session->ice.ice_user ? (rtp_session->ice.rready && rtp_session->ice.ready) : 1;
if (!dtls->bytes && !ready) {
//switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(rtp_session->session), SWITCH_LOG_ALERT, "Ice not ready");
return 0;
