VVX 300 Allow Traffic only from single IP

[rosenbergs]

In my VVX 300, is there any way I can restrict SIP traffic to a single IP?

Hello @rosenbergs ,

Welcome to the Poly Community.

I am not sure what you are exactly after but have a look at this FAQ post:

Oct 24 2014 Question: How can I prevent Ghost calls or tools like sipvicious or nuisance Cisco calls ringing my phone?

Resolution: Please check => here <= or Security Center: Security Bulletin Relating to Worldwide Botnet Dialing H.323-Capable Systems

The requestValidation will allow the phone to only accept inbound traffic from the IP where it is registered to.

Thanks for your reply. 

So, I would put in 

<web voIpProt.SIP.strictUserValidation="1"/>

 But where am I putting this in?
