Hi everyone,
Hope you're doing well.

Suddenly, on Bria app I get SIP error 408 and no inbound calls are not not working. When I checked the logs, it has only one line which says: mod_logfile.c:192 New log started. So I guess there's something which is blocking every requests. I checked the server's firewall configuration and I didn't see any problem there. And I contacted the server administrator and they said there's no external firewall that would be blocking any communication to the server. Any idea is appreciated.

FYI, I'm new to PBX.
 
A 408 is a request timeout so your SIP packets are not getting from end to end. There could be lots of reasons but one of the first things to check is Fail2ban. If you log in to a shell on your server and issue an iptables -nvL you will quickly see if the IP address for your Bria is in a jail.
 
Thanks a lot for your message. This is output of iptables -nvL:

Do you see something wrong? I disabled iptables to see if it works but nothing happened. What do you think?
 
The "Chain f2b-" entries are the fail2ban jails, there is nothing in any of them. Good to look though.

You will need to do some basic network diagnostics ping etc. to try to find out what is happening.
 
There’s a bug in Bria Enterprise at the moment and maybe other versions of Bria but only with the mobile app and when using a carrier that assigns you an IPv6 address
 
Thanks for your responses. Bria and my other Freeswitch servers can not connect to my PBX server. So I think there's a connectivity problem. Could you please let me know how can I resolve that since I'm new to all of these stuff?
