Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
In the event of a user-originated emergency call, the modem will automatically put itself into
Emergency callback state. The modem will remain on the same system to be able to receive
callbacks from emergency personnel. The modem behavior during Emergency callback state
depends on the factory-provisioned mode--Timer Reset Mode or Basic Mode. The mode is
carrier-specific.
AT+WSOS can only query the Emergency callback state. The user cannot exit Emergency
callback state using the AT+WSOS=0 command. Emergency callback state is exited when:
AT+WSOS=0 must be used to exit Emergency callback state. While in Emergency callback state,
only calls to emergency numbers can be established. Emergency callback state is exited when:
If neither Timer Reset Mode nor Basic Mode has been set in the factory, then AT+WSOS will
return ERROR.
In addition to 911, other emergency numbers are supported by the modem software. See the
AT$WEMER command.
