A firewall is not going to help. On many SIP telephones this can be an issue. On Yealink they have a setting labeled “Accept SIP trusted Server only” which will cause those ‘ghost calls’ to stop. I am not sure why they do not have it enabled. Seems this should be default on all SIP telephones these days.
I have not seen such a setting on LinPhone, but I would of thought such security would be in the code.

They will send calls to random IP's and if they find a vulnerable system they make calls on the phone systems owner's expense. Some phones have an option to disable such calls but I don't see one on Linphone (at least not in the version I have here). A simple firewall should be able to block such calls.

Recently I keep getting incoming calls that just don’t stop. This has happened with some but not all of us using this. Any idea of how to change settings to stop this? The second thing is that occasionally I can’t get an ip address on some installs. Instead I get a weird number after my name instead of an IP. Would really love to email with someone because this works great for me and I would like to fix these small but very annoying problem.
