Webrtc using puplic ip not hear


#1

Hello everyone
I have use UCM6202 firmware 1.0.19.27.
when I call using webrtc using public ip it has no voice.
I using google chome Version 77.0.3865.90 (Official Version) (64 bit) and the latest firefox but it’s the same.
Is that a problem of UCM.

you activated both voice and video codecs?
that you did the NAT with the ACL?

Hi
I have activated both voice and video codecs.
I using ipphone video ok, but webrtc not ok.


#4

you activated the appropriate NAT as I wrote on them?

try to use WebRTC inside the LAN, if it works properly you know that the problem is external, so Firewall not set correctly


#5

The capture is not complete as it only shows the 3370 and UCM communications and not that to the outside. You need to do a capture using all interfaces.


#6

Hi
I have use webrtc insite the LAN ok, webrtc problem is external.
I do not have a firewall, so a firewall is not a problem, because i can use external ip phone and softphone ok


#7

ok will capture all UCM and PC


#8

not having a firewall is a GRANT error, you NEVER expose to the whole world one or more ports, for reasons of security and smooth operation.
Moreover, without a firewall you can not monitor where exactly the problem is, if locally webrtc works at this point the problem you have to search outside of UCM.

thanks @damiano70 I am running a test, so I don’t go through the firewall to see if the problem is with the firewall.

I remember that GS have problem with NATing SDP (or rather lack of it).
Log - data is encrypted, not much can read.

If you can switch to http and do again test with log and check if SDP is NATed or not.

I had no issue in using HTTPS and port 8089 with a fqdn for WAN access. I was using Chrome Version 77.0.3865.120 (Official Build) (64-bit) at the remote site and a GXV3275 across a VPN for the other end. The only thing I had to do was to unmute the Chrmoe side of things as when it first starts the microphone is muted.

I also tried Firefox 69.0.3 (64-bit) and had no issue.

You did not state what other device or web client was in use in the conference as I assume there must have been at least one other.
