2.16.9 Call Offer
Description
The CALL OFFER is the same service as the CAMP-ON that is described at Section 2.4.5(see Ref.1),
except that the camp on is executed on the networking connection environment. The term of CALL
OFFER is used at H.450 protocol standard specification.
When a station user make a net call to a busy station that is located on other networking system, busy
tone is heard. At that time, the caller can give a signal to the busy station by using of 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.
The figure 2.16.9 describes the call offer operation on the networking connection environment. At the
first step, the station 100 makes a net call to the busy station 202, but it hears the busy tone. To
execute the call offer service, the station 100 dials the camp-on code ‘
Ú
’, at the second step. The call
offer request is sent to station 202, and it receives a camp-on signal tone, at the third and fourth steps.
Two stations can make a conversation, when the station 202 is pressing the
[HOLD/SAVE]
button.
