Other Useful Features u z DTMF Tones The DTMF function is used to control answering machines or any other telecommunication devices. Lift the handset. Make an internal or external call to reach the desired device. When your call is answered you can continue to dial digits which will be sent as DTMF digits (tone signals) to the called device in order to activate the desired functions. Networking Networking is the connection of several premises within a company. The connection can be set up via leased lines, public lines, Local Area Network (LAN) or Wide Area Network (WAN). Ask your system administrator about details regarding networking. Ô Inquiry *61* IP Calls IP Calls are internal calls sent via an internal data network (LAN or WAN) and the transfer of data and voice is made on the same line. If you are connected to an internal data network the IP connection is made automatically. To minimize the traffic on the network the speech quality is decreased. If the speech quality is not acceptable you can disconnect the IP call and switch to a non-IP call (alternative network). The switch from the IP net to the non-IP net is made during the call, so the call does not have to be disconnected. If you want to switch to a nonIP net during the call: Press. Dial. During the procedure the other party is put on hold. When the procedure is ready you will receive a special ringing tone and the call is resumed in the non-IP net. Note: A switch to a non-IP call can only be performed if the original call is an IP call, otherwise you will receive a Blocking tone. 78 BusinessPhone - Dialog 4220 Lite / Dialog 3210
