Phone Call (TMO)
Half-duplex telephone calls are not supported.
4.3.2 Receiving a Telephone Call
Incoming Telephone calls (Land Gateway to Mobile) will use on/off hook signalling. The terminal will
extract the gateway ID from the call set-up signalling, to determine whether to enter Phone or PABX
mode upon receiving the call.
4.3.3 Call Restoration in Phone Call
If the terminal roams while the user is in an active phone call, and it is possible to perform
announced cell reselection, announced cell reselection will be employed as described in Paragraph
10.4 "Roaming" and call restoration procedures will be performed.
4.3.4 Calling Line Identification Presentation (CLIP)
If the terminal is provisioned to display the calling party, the calling party number will be transported
as part of the incoming call set-up signalling (as described in [Ref 1]) and shown on the terminal
display to the user.If the calling party ID is programmed in the terminal with a corresponding name,
the name will be displayed to the user in addition to the number.
Note: It is expected that the number sent by the SwMI will be in a form that can be used by the
called user to call back the calling party at some other time. Thus, for instance, the number
can be stored by the user as-is in the address book.
If the calling party number is not present in the incoming call set-up signalling, a blank line is
displayed to the user in its place.
