Which chrome version? Try restarting it or on canary to see if there's differences. Em qui, 14 de set de 2017 às 02:24, Richard Chan < richard@treeboxsolutions.com> escreveu:
Hi,
I'd like to get your opinion on whether this WebRTC failure to connect points to a Chrome/VC or FS bug.
FreeSWTICH: 1.6.19 Verto Communicator: from v1.8 branch Chrome: 59-61
Reproducer: 0. Chrome and FS on a local LAN 1. In VC, disable STUN as environment is local LAN 2. Chrome sends 2017-09-14 11:48:33.658249 [DEBUG] mod_rtc.c:389 () State Change CS_NEW -> CS_INIT 2017-09-14 11:48:33.658249 [DEBUG] switch_core_session.c:615 N/A set UUID=b138714b-740a-de23-101c-c76d5676a6d4 2017-09-14 11:48:33.658249 [NOTICE] switch_channel.c:1104 New Channel verto.rtc/3000 [b138714b-740a-de23-101c-c76d5676a6d4] 2017-09-14 11:48:33.658249 [DEBUG] mod_verto.c:3661 Remote SDP verto.rtc/3000: v=0 o=- 3881351537341052870 2 IN IP4 127.0.0.1 s=- t=0 0 a=group:BUNDLE audio video a=msid-semantic: WMS Tub3STBaDw6tNMrINhAyvJBWK96IeIanerjj m=audio 9 UDP/TLS/RTP/SAVPF 111 103 104 9 0 8 106 105 13 110 112 113 126 c=IN IP4 0.0.0.0 a=rtcp:9 IN IP4 0.0.0.0 a=ice-ufrag:VU1P a=ice-pwd:davKC7PLYeQ04ZkN4TNvGo9s a=ice-options:trickle a=fingerprint:sha-256 79:A5:79:AE:62:B9:7F:00:5F:0C:04:C1:18:81:C4:09:ED:47:3B:1B:0A:3C:2F:F2:7B:6F:D5:E7:3C:DA:E0:2C a=setup:actpass a=mid:audio a=extmap:1 urn:ietf:params:rtp-hdrext:ssrc-audio-level a=sendrecv a=rtcp-mux
3. FS replies

4. With STUN on, it connects successfully. Chrome sends the external NAT address (STUN discovered). This seems unnecessary for a local LAN.
5. For Firefox+VC without STUN, the verto.invite contains all the local LAN addresses and it connect successfully.
Any suggestions? Should Chrome+VC without be expected to work w/o STUN on a local LAN while sending c=IN IP4 0.0.0.0?
