Siemens MC55 AT manual No Carrier

Notes

•Due to its restrictive value range, indicator "call" does not clearly reflect specific call states (such as alerting, active, held etc.), but rather serves to trigger the application to retrieve the new call status from the list of cur- rent calls with the AT commands AT^SLCC, AT+CLCC or AT^SCNI.

•If AT^SCFG setting <succ>="verbose", indicator "call" will be issued also when a traffic channel is estab- lished, or when a call enters states "terminating" or "dropped" (see Call Status Information).

In these cases, the relevant information about the cause of the display is available only from AT command

AT^SLCC.
