Command Description
This command can be used to set up outgoing voice, data or fax calls. It also serves to control Supplementary
Services. The termination character ";" is mandatory to set up voice calls or to send *# codes for Supplementary
Services. It must not be used for data and fax calls.
Additional notes on the responses returned after dialing with
:
• For voice calls, you have the choice of two different response modes that can be selected with
=1 (factory default) causes the ME to respond once the call setup is completed either successfully
("OK") or unsuccessfully ("NO CARRIER", "NO DIAL TONE", "BUSY").
=0 causes the ME to return "OK" immediately after dialing was completed (i.e. before call setup ter-
minates successfully or unsuccessfully).
• For data connections, call setup always terminates when the call has been established (indicated by the result
code "CONNECT <text>), or when it fails (indicated by "NO CARRIER"). The settings of
apply.
Different call release indications:
• Upon termination, an outgoing fax or data call may show a different result code than a voice call would show
under identical conditions. In order to track down the actual reason for call termination,
should be used for all applicable connections.
