RE: Ghost Calls from Port Scanning

I've Disabled "allow i.p calls"

and changed the "Local SIP Port" under advanced to something random.

Is there anything else i can do to prevent this?, Can anything else be entered on the phone to prevent these calls? Apart from changing the sip port from 5060.

Or can something be changed on Elastix?

Would buying a a decent router help?

Cheers


The only time we seem to have this happen is when we are deploying a single phone into a home network situation. In deployments in an office network environment we have only ran into it when there are holes in the firewall or the particular phone it is affecting is in DMZ mode.
