Configuring Eight Calls per Button (Octo-Line)
The octo-line feature supports up to eight active calls, both incoming and outgoing, on a single button.
Eight incoming calls to an octo-line directory number ring simultaneously. After an incoming call is
answered, the ringing stops and the remaining seven incoming calls hear a call waiting tone.
After an incoming call on an octo-line directory number is answered, the answering phone is in the
connected state. Other phones that share the directory number are in the remoteMultiline state. A
subsequent incoming call sends the call waiting tone to the phone connected to the call, and sends the
ringing tone to the other phones that are in the remoteMultiline state. All phones sharing the directory
number can pick up any of the incoming unanswered calls.
When multiple incoming calls ring on an octo-line directory number that is shared among multiple
phones, the ringing tone stops on the phone that answers the call, and the call waiting tone is heard for
other unanswered calls. The multiple instances of the ringing calls is displayed on other ephones sharing
the directory number. After a connected call on an octo-line directory number is put on-hold, any phone
that shares this directory number can pick up the held call. If a phone is in the process of transferring a
call or creating a conference, other phones that share the octo-line directory number cannot steal the call.
As new calls come in on an octo-line, the system searches for the next available idle line using the
huntstop chan
tag
command, where
tag
is a number from 1 to 8. An idle channel is selected from the
lowest number to the highest. When the highest number of allowed calls is received, the system stops
hunting for available channels. Use this command to limit the number of incoming calls on an octo-line
directory number and reserve channels for outgoing calls or features such as call transfer or conference
calls.

•
Configure only dual-line mode
