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 Changing Emergency

Line Settings on page 41.

To make emergency calls:

• Enter the emergency number for your geographical location, and then press the

green key .

When you make emergency calls, always press the green key regardless of

whether your emergency calls are routed via a landline or over the Internet.

IMPORTANT: You cannot make emergency calls in the following situations:

• Firmware update is in progress

• Handset batteries are drained

• Power failure

• Handset is out of range of the gateway
