For incoming calls, if an account is configured and registered, all incoming calls for that account will attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use,
A LINE is defined as “ACTIVE” when it is making or receiving a call, and its corresponding LINE LED is lit up in solid RED.
4.3.3 Making Calls
There are four ways to make phone calls:
1.Make Handset/SPEAKER/Headset off hook, or press the available LINE key to select a SIP account, the corresponding LINE LED will light up in solid red. Enter the phone numbers and press the SEND key.
2.Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the correspond- ing LINE LED will light up in solid red. Press the SEND button to redial the last number called.
3.Press the OK to bring up the Main Menu, select Phone Book, browse phone book to the person you want to dial, press OK to select and OK again when Dial is selected. The call will dial out in SPEAKER mode. (Right now this only applies to primary a/c which is LINE 1)
4.Paging/Intercom: This is ONLY valid if the SERVER/PBX support this feature and both phone and PBX (for example, Asterisk) are configured correctly:
Make Handset/SPEAKER/Headset off hook, select the LINE key to related feature available account, then press OK key again to see LCD showing: LINEx: PAGE USING. Now input the phone number you want to Page/Intercom and press SEND key.
NOTE:
•Once off hook and key pressed, the dialed number will be displayed on the LCD and the corre- sponding DTMF tone will be played out.
•If the “SEND” button is not pressed after the phone number pressed, the phone (by default) will wait for 4 seconds (no key entry timeout) before sending all digits out and initiating the call.
4.3.4 Making Calls using IP Address
Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones if
•Both phones have public IP addresses, or
•Both phones are on a same LAN/VPN using private or public IP addresses, or
•Both phones can be connected through a router using public or private IP addresses (with nec- essary port forwarding or DMZ)
