IP PHONE FOR MX-ONE™ 5 Outgoing Calls This chapter describes how to make outgoing calls, and lists the options available to you when you receive a busy tone or no answer. 5.1 Making Calls You can call both internal and external numbers from your phone. To dial an external number, you must first enter the external access code. Note: The external access code is one or more digits used in your office to get a line for external calls, for example 0 or 00. To make a call, do the following: 1) Lift the handset and wait for a dial tone. 2) Dial the number. • For internal calls, dial the extension. • For external calls, enter the external access code and dial the external number. It is possible to use short numbers for numbers that you call often, see section 5.5 Speed Dialing on page 45. 5.2 5.2.1 39 When You Receive a Busy Tone or No Answer If you call an internal number and you receive a busy tone or get no answer, or if all external lines are busy, you can either try again later, or order automatic callback, call waiting, or intrusion. Callback When you order callback for a busy extension, you will be called back as soon as the extension or line becomes free. If you order callback when there is no answer, you will be called back when the extension has been used the next time. Note: When you return to the office, you can tell the system that you are present by lifting the handset and immediately replacing it. You can order automatic callback in the following cases: 6/1553-DBC 433 01 Uen D2 2014-03-26
