When your phone is called, this feature rings up to five additional phone numbers in sequence. The initial BCP number will ring and after a preset number of rings the next phone number will ring and then the next number(s) until the call is picked up or the call goes to voicemail or other no-answer processing from the main number. The caller can wait until the call is answered or leave a message at any point by pressing a key on their handset.
If the any of the lines are answered while ringing (including voicemail from any of the lines in the sequential ring list) then the Sequential Ring list will stop and the call is completed. If no lines are answered, then the call is sent back to the main line for processing (Voicemail, CFNA, etc.)
