Unable to make outgoing calls



Unable to make outgoing calls on current ISP however able to mobile data connection to make phone calls. Is there any specific port or IP needs to unblocked.


Is this about Jitsi Desktop? If that is the case, check this out https://desktop.jitsi.org/Documentation/FAQ#fragmentation, just disable few unused codecs, maybe this is the problem, different networks and different MTU.


I tried but it still did not work.


Can you upload the logs https://desktop.jitsi.org/faq#logs from a failed call, to see what are the errors?
