    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.

    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.
