Ringing Options
On multiline telephones, calls forwarded to an extension ring with an
abbreviated ring at the forwarding extension and also ring at the
destination extension. On single-line telephones, calls forwarded to an
extension ring at both the forwarding extension and the destination
extension. On both multiline and single-line telephones, calls forwarded
to a telephone number do not ring at the forwarding extension.
Outside calls received at the forwarding extension ring as inside calls at
the destination extension (one ring) and do not receive the normal
distinctive ring for an outside call.
For ringing options set to Immediate Ring, calls are sent to the
forwarded extension immediately. For Delay Ring, calls are delayed
before being forwarded. For No Ring, calls are not forwarded. In
Release 4.0, if a button is set to Delay Ring, calls are forwarded after
both the Delay Ring and Forwarding Delay. The two delays are
cumulative.
Abbreviated Ring is not operable for calls to the calling group
extension, because a calling group member who is active on a call is
considered unavailable for incoming calls. In Hybrid/PBX mode, calling
group members should program SA buttons for Immediate Ring.
Headset Auto Answer does not automatically answer calls ringing on
buttons programmed for No Ring on an MLX telephone; the user must
select the button manually to answer the call. When Abbreviated Ring is
enabled, the user hears the abbreviated ring if another call rings while
the user is on a call.
The ringing patterns for tip/ring devices connected to an MFM are those
of an MLX telephone rather than a single-line telephone—one ring for
inside calls, two rings for outside calls, and three rings for priority ring or
transfer return. Personalized Ringing patterns cannot be programmed
for an MFM. Centralized telephone programming must be used to
program Ring Timing options (Immediate Ring, Delay Ring, or No Ring).
When Night Service is turned on, calls received at a Night Service
group member's telephone ring immediately even if the line buttons are
programmed for Delay Ring or No Ring. When Night Service is turned
off, telephones return to their programmed Ring Timing options.
A reminder call overrides programmed Ring Timing options (Delay Ring
and No Ring) and rings with a priority ring at an SA or ICOM button.
Transfer returns ring until answered and do not receive abbreviated
ringing.
