AcceptUnregisteredCalls security implications

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Everyone,
    What are the security implications:

<quote src="http://www.gnugk.org/h323manual.html";>
AcceptUnregisteredCalls=1
Default: 0
With this feature enabled, the gatekeeper will accept calls from
any unregistered endpoint. However, it raises security risks. Be
careful to use it.
</quote>

What I can see are the following scenarios:

If you have CallUnregisteredEndpoints, someone will likely be
able to use the GK to anonymize their calls... (If proxying is
enabled???)

If you have a GW to the PSTN, they can call the PSTN on your dime

Does anyone have any feedback on this?  I think the manual is a
little lacking in what this means.

Cheers,
Derek
