Hi

STUN std ports are UDP 3478 and 3479 just block it on firewall (if this is what you mean by disabling STUN-related communications)

Thanks

Disable STUN for all SIP phone set as well. After that your SIP phone at internet will unable to use this services. Unless all the things are setup at internet without NAT.

Thank you for the answers!

I must define question more exactly. Can I disable 3CX STUN activity?

Yes, you can

How???

1. By using advises above.
2. By entering non-valid stun server's address

By using non-valid STUN IP address.... Hmm... I can't avoid undesirable network activity by this method.

If you set it to 127.0.0.1 -- you can.
