When I miss a call from the outside world, the caller ID shows me the
10-digit phone number (e.g. 408564000), and that’s how it shows up in
the Missed Calls list as well. However, if you go to Missed Calls (by
pressing the down arrow when the phone is idle) and hit the "Dial"
option for one of those phone numbers, the phone will try to literally
dial 408564000 , which fails immediately of course, because you have
to dial 8408564000 to reach that number. So the dial back feature
doesn’t actually work, does anyone know how I would actually fix this?
I am using polycom 550 sip phones.
