MAKING AND ANSWERING PHONE CALLS
HANDSET, SPEAKERPHONE AND HEADSET MODE
The BT200 handset can be toggled between speaker mode (hands-free) or headset mode. To toggle
between the handset and speaker/headset, press the Hook Flash in the handset cradle or press the
SPEAKER button.
PLACING A TRADITIONAL PHONE CALL
There are four ways to place a call:
1. Use handset, headset or press SPEAKERPHONE button and dial.
2. Press the SEND button directly to redial last number. Last dialed number will be displayed on the
LCD as the number is dialed.
3. Browse the CALLED/CALLER history, select the number using the navigation keys and press
SEND button to place the call.
4. Use the menu key to browse the “CALLED/CALLERS” menu to scroll through the last 10
numbers dialed or received. Select number using the navigation keys and press SEND button to
place the call.
Examples:
• To dial another extension on the same proxy, such as 1008, pick up handset or press speaker, dial
1008 and then press SEND.
• To dial an outside number such as 626-666-7890, enter prefix if necessary and dial number and
press SEND. Check with your VoIP provider for more information about prefixes.
PLACING CALLS USING AN IP ADDRESS
Direct IP calling allows two parties using a BT200 and another VoIP device to talk with each other in an
ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones if:
• both phone/VoIP device have public IP addresses, or
• both phone/VoIP device are on a same LAN/VPN using private or public IP addresses, or
• both phone/VoIP device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ)
PLACING A DIRECT IP-IP CALL
To place a direct IP to IP call, first off-hook, then press the “MENU” key, then enter a 12-digit target IP
address to make the call. If port is not default 5060, destination ports can be specified by using “*4”
(encoding for “:”) followed by the port number.
Examples:
• If the target IP address is 192.168.0.10, the dialing convention is MENU 192 168 000 010 followed
by pressing the “SEND” key or wait for seconds in the No Key Entry Timeout.
• If the target IP address/port is 192.168.1.20:5062, then the dialing convention is MENU_key
192168001020*45062 followed by the SEND key or wait for 4 seconds.
