Thanks a lot, that’s the solution. Von: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] Im Auftrag von Marcel Haldemann Gesendet: Mittwoch, 24.

Then just go to “https://yourhostname.com/vc” and you should have a working verto server and client. Note: change the default password to get rid of the 10 sec delay or remove the delay in the dial plan.

The certificate is generated like described here: https://webrtc.freeswitch.org/verto/index.html#page-main And the ca.crt is installed on the client pc. But the following error message is again: 2016-08-24 15:03:47.044880 [INFO] mod_verto.c:4025 192.168.241.2:43246 Client Connect. 2016-08-24 15:03:47.044880 [INFO] mod_verto.c:1978 192.168.241.2:43246 Starting client thread. 2016-08-24 15:03:47.084876 [DEBUG] mod_verto.c:1825 192.168.241.2:43246 WS SETUP FAILED [] 2016-08-24 15:03:47.084876 [INFO] mod_verto.c:2005 192.168.241.2:43246 Ending client thread. 2016-08-24 15:03:47.084876 [INFO] mod_verto.c:2013 192.168.241.2:43246 Thread ended What can I do? Is the certificate the problem? The Client PC and the Freeswitch PC are in the same Network Cluster. The Freeswitch PC is a Debian 8.5 system. Thanks a lot Alex
