Voice Call States

Psion Teklogix Mobile Devices SDK Developers Guide 223

Alerting

Applies to: outgoing calls

The called party is being notified that there is an incoming voice call. Typically this means that the

called phone is ringing.

Incoming

Applies to: incoming calls

This state applies to an incoming voice call when there is no active voice call. See “Audio for

Voice Over WWAN” on page 228 for instructions on creating a ring tone.

Waiting

Applies to: incoming calls

Only available if the WWAN provider supports this feature.

This state applies to an incoming call when there is an active voice call, or a previous call in the

incoming state.

No Answer

Applies to: outgoing calls

The called party did not answer the call within a specified, network defined, time.

This state is not often returned as many calls are automatically answered by switchboards and

answering systems.

No Carrier

Applies to: outgoing calls

The Psion Teklogix computer could not connect to the WWAN network.

Busy

Applies to: outgoing calls

The called party is busy and does not answer the call.

This state is not often returned as many calls are automatically answered by switchboards and

answering systems.

Supplementary Accepted

Applies to: outgoing calls

Supplementary services can be configured using codes entered on the keypad of a telephone.

These codes are numerals preceded by *#. An application can insert these codes into a dialing

string. This status indicates that the network accepted one of these codes.

For a list of supplementary services see “WWAN Supplementary Services” on page 216

. For a list

of codes, consult your network provider.

Normal Termination

Applies to: incoming and outgoing calls

The voice call terminated. This is returned by any call where the modem detects that a call, that

has been active, no longer exists.
