I am trying to setup up a SIP line via SIP/IP trunk ports on my Nortel BCM50 Rls 6 phone system on my network.
I have forwared port 5060 in the Hiltron to my BCM's IP address and now getting hammered with bogus calls every 30 seconds where nobody is on the line.
I have not even registered/logged in with a SIP provider yet!
Is there some way to allow 5060 but only from a certian server, sipgate.co.uk in this case.
Residential Gateway is enabled
UPnP is enabled
Thanks
