I've noticed that some "unknown" caller keeps calling my number and that gets translated into "asterisk" in the callerid of my phone and the obihai call logs.
This is my setup.
Google voice > vestalink > obihai
Google voice logs show "unknown", vestalink incoming call logs show nothing...it's just a "-", and obihai shows "asterisk".
What is going on here? Anybody having similar issues?
The most annoying thing is that the caller never leaves a message.
