Call Offer
Call Offer is the same service as Camp-On, except that the Camp-On is executed in a
Networking connection environment at the H.450 protocol standard specification.
When a Station User initiates a Net Call to a busy Station that is located on another networking
system, a busy tone will be heard. At that time, the caller can give a signal to the busy station
by using the Call Offer service. The busy station (through the receiver or on speakerphone) is
notified of the call waiting by a camp-on tone and flashing LED of the [HOLD/SAVE] button.
Operation
To activate Call Offer:
1.
Dial a valid Station number on another networking system; if busy, the caller will hear a
busy tone.
2.
Press the Camp-On code (*); the busy Station will receive an off-hook muted ring (the
Calling Station will hear a ring-back tone instead of a busy-tone).
To answer the Call Offer:
1.
Press the flashing CO line button while receiving a muted ring.
-or-
The muted ring is changed to normal CO ring when you go on-hook state.
2.
Then Station User can answer the offered call.
