Examples of Direct IP Calls:
a) If the target IP address is 192.168.0.160, the dialing convention is
*47 or Voice Prompt with option 47, then 192*168*0*160.
followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case,
the default destination port 5060 is used if no port is specified.
b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
*47 or Voice Prompt with option 47, then 192*168*0*160*5062
followed by pressing the “#” key
if it is configured as a send key or wait for 4 seconds.
NOTE:
When completing direct IP call, the “Use Random Port” should set to “NO”. You cannot make
direct IP calls between FXS1 to FXS2 since they are using same IP.
CALL HOLD
Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).
Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash”
button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.
CALL WAITING
Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle
between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press
the “flash” button to toggle between two active calls.
