5.3.7Call Transfer
Two transfer operations are supported.
5.3.7.1 Blind Transfer
User can transfer an active call to a third party without announcement.
User presses the “TRANSFER” button and if the other voice channel is available (i.e., there is no other active conversation besides the current one), user will hear a dial tone. User can then dial the third party’s phone number followed by pressing SEND button.
NOTE:
•“Enable Call Feature” has to be configured to “Yes” in web configuration page in order to make the features to work.
A can hold on to the phone and wait for one of the three following behaviors:
•A quick confirmation tone (temporarily using the call waiting indication tone) follows by a dial tone. This indicates the transfer has been successful. At this point, the user can either hang up or make another call.
•A quick busy tone followed by a restored call (On supported platforms only). This means the transfer has failed due to the failed response sent from server and the phone will try to recover the call. The busy tone is just to indicate to the transferor that the transfer has failed.
•Busy tone keeps playing. This means the phone has failed to receive the final response and decide to time out. Be advised that this does not indicate the transfer has been successful, nor does it indicate the transfer has failed.
5.3.7.2 Attended Transfer
User can transfer an active call to a third party with announcement.
User presses the “FLASH” button and hears a dial tone, then dial the third party’s phone number followed by pressing “SEND” button. If the call is answered, press “TRANSFER” to complete the transfer operation and hand up, if the call is not answered, pressing “FLASH” button to resume the original call.
NOTE:
•When Attended Transfer failed, if A hangs up, the BudgeTone phone will ring user A back again to remind A that B is still on the call. A can pick up the phone to restore conversation with B.
