Making and Answering a Call
Handset, Speakerphone and Headset Mode
The call can be switched between the handset and speaker/headset modes. To switch
between handset and speaker/headset mode, press the hookswitch or SPEAKER.
Multiple SIP Accounts and Lines
The ET523 can support up to four independent SIP accounts. Each of the four line keys
(LINE1–LINE4) is mapped to one SIP account. In off-hook state, when you press the
corresponding Line key or continuously press the same line key, the phone will switch
among the four accounts. If the name of an account is configured, then it is displayed on
the LCD and a dial tone is heard.
For example: configure Account Name of the four SIP accounts as AAA,BBB,CCC
and DDD. Ensure each account is activated and registered on the VoIP server or
IP-PBX. When LINE1 is pressed, you will hear a dial tone and see AAA on the LCD
display; when LINE2 is pressed, you will hear a dial tone and see BBB on the LCD
display, and the operation result is as same as pressing LINE3 and LINE4. The same
function can also be performed when you press any idle Line key continuously. The
LCD displays the used account and the dial tone can be heard.
To make a call, select the line you wish to use. The LED of the corresponding line will
light up. Switch lines before dialing by pressing the same LINE key continuously until
the desired account is displayed on the LCD and the dial tone is played.
For example: when LINE1 is pressed, the LCD displays AAA; If LINE1 is pressed
twice, the LCD displays BBB and the subsequent call will be made through SIP account
2BBB.
When the phone is idle, press the corresponding key to answer the incoming call
designated to a specific account. If the corresponding line is occupied, the ET523 will
