Setting up Call-Suspend
The Call Suspend feature allows the telecom manager to reduce communication costs by bringing down
the ISDN/IP connection when all phones are inactive for a configurable period of time. When the line is
disconnected the phones indicate that they are in the Call Suspend mode. Whenever a user goes off-
hook or an incoming call occurs, the ISDN/IP connection is brought back up and all phones are taken out
of Call Suspend mode.
The Call Suspend feature operates with the assumption that if the ISDN connection is brought down, it is
possible to get busy signals from the ISDN/IP network preventing the EXTenders from communicating
and causing an interruption of telephone service to the branch office. This assumption leads to setting the
Call Suspend timer to a value that does not allow the ISDN/IP connection to go down during normal
business hours.
The expected usage pattern for the ISDN/IP connection is that at the beginning of the business day, the
phones are brought out of Call Suspend mode bringing up the IDSN/IP connection when the first user
either goes off-hook or an incoming call arrives. The ISDN/IP connection remains up for the remainder of
the business day because all phones are not idle longer than the Call Suspend timeout value. At the end
of the day, all phones become inactive for the Call Suspend timeout value and the ISDN/IP connection is
brought down. If anyone works late or comes in early, normal usage brings up the ISDN/IP connection
again.
