[asterisk-users] Ghost ringing

[jfratantoni at iswan.net]

Hey Mike,

I originally thought the same thing; however, I have swapped their phone
with another one here in the office. The one on-site is still experiencing
issues; the office isn't. If it were firmware, I'd assume the issue would
'travel' with the phone. Though I can give re-flashing it a shot.

Thanks,
Joe
