service must be supported by the service provider. If
your service provider does not support this service,
see below the instructions on explicit call transfer.
i You can put all parties on hold by entering
FLASH and key “2”.
Explicit Call Transfer
With the presence of two established calls, pressing
FLASH “4” keys connects the two distant parties
and disconnets the GSM Terminal from both
calls. However, some service providers implement
a proprietary solution for explicit call transfer using
special service codes. You can use special explicit call
transfer service codes between two established calls
by following these steps:
• Put the calls in conference call by pressing
FLASH and the key “3”.
• Put the calls on hold by pressing FLASH and
the key “2”. You should get a dial tone.
• Dial the explicit call transfer code to complete
the explicit call transfer operation.
GSM RELATED SUPPLEMENTARY SERVICES
The GSM Terminal provides transparent access to all
standard GSM Supplementary services. Since some
of the services need an extra subscription, consult
your service provider for the availability of these
services.
Table 2 on page 12 lists the services supported by the
GSM Terminal and instructions on how to activate
and deactivate them, as well as on how to query the
status of each service.
i Successfully completed actions are indicated
by a single acceptance tone while incomplete
or unsuccessful supplementary Service requests
are indicated by three monotonically increasing
failure tones.
i Status queries will provide a single tone
indicating an activated service and two
monotonically decreasing tones (“negative
acknowledgement tone”) indicting a deactivated
service.
