Making and Answering Calls

Making Emergency Calls

The default setting of emergency calls is over the landline (the LINE port on the
gateway). Check that you have a working landline connection for emergency calls. If
you are using VoIP calls exclusively you should change the emergency call setting to
a registered SIP account.

Note: It is recommended that you check with your System Administrator for the
method of routing emergency calls in your network.

For more information on setting the emergency call line, see
