Hi All,
Not sure if this is the correct place to add this question.
We have a client with a UC320 system, we have approx. 17 handsets with 2 x SIP trunks.
The system works perfect, apart from they are getting calls from random numbers every few minutes.
Our SIP trunk provider states that port 5060 is wide open to the Internet and this would be the allowing all calls.
Can anyone please advise how this port can be locked down on the UC320
All help would be very much appreciated.
Regards
Andy
