Prostar 816 On-hold ring-back feature
We have owned a Prostar 816 phone system for about 8 years and never had an on-hold ringback feature on our system to any of the phones.
Suddenly about a month ago whenever we put someone on hold, within 20 seconds the phone is ringing back. First to the original person then, if no one picks up it rings back to reception.
How can I program this to stop?
