Hello,
I am running PIAF at RentPBX. I have 30 extensions sitting at HQ behind a Cisco 5520. I have 20 remote users. These remote users are not connecting via a VPN, they are straight connecting to RentPBX.
These guys are getting random sip calls at all times of the day. Their phone will show a call from an IP to them that is not from anywhere else. I am not sure if they are attempts through RentPBX down to the extension or attempts at their end from script kiddies.
All the phones are Polycom VVX310s.
Is there any setting anywhere I can do to only allow calls from our RentPBX server and reject the rest?
Thanks,
dave
