VOIP with works phone

Hi everyone, I just plugged my works phone into my router and I can make calls, however. I keep getting multiple calls (almost constantly) but when I answer there is no one there. Anyone know why this is happening and how I can stop it?
thanks
Brian

Its caused by sip 'probes' trying to find vulnerable voip devices. Using the plusnet router, I'm afraid theres not much you can do to prevent it. If you have an active sip connection, then the router will allow sip packets from anywhere.
As a start you might consider a replacement router with the ability to disable the sip alg.

Depending on the model of phone it may be possible to tell it to only accept inbound calls from a specific SIP server. You will probably need admin access to the phone settings to do so.
Search for "VOIP ghost calls" together with your phone model and see if there are any configuration suggestions.
