Completion on
Busy Subscriber
(CCBS)
When you make a phone call but hear a busy tone, Call Completion on
Busy Subscriber (CCBS) allows you to enable auto-callback by pressing
5 and hanging up the phone. The P-2812HNU-51c then tries to call that
phone number every minute since after you hang up the phone. When
the called party becomes available within the CCBS timeout period (60
minutes by default), both phones ring.
• If the called party’s phone rings because of CCBS but no one
answers the phone after 180 seconds, you will hear a busy tone.
You can enable CCBS on the called number again.
• If you manually call the number on which you have enabled CCBS
before the CCBS timeout period expires, the P-2812HNU-51c
disables CCBS on the called number.
• If you call a second number before the first called number’s CCBS
timeout period expires, the P-2812HNU-51c stops calling the first
number until you finish the second call.
Select this option to activate CCBS on the P-2812HNU-51c.
