the last few digits (last octet) of the target phone's IP address. This is possible only if both phones are
under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP server.
Controlled static IP usage is recommended.
To enable Quick IP Call Mode, go to phone's Web GUI->Settings->Call Features, set "Use Quick IP Call
Mode" to "Yes". Click on "Save and Apply" on the bottom of the Web GUI page to take the change. To
make Quick IP Call, take the phone off hook first. Then dial #xxx where x is 0-9 and xxx<255. Press # or
SEND and a direct IP call to aaa.bbb.ccc.XXX will be completed. "aaa.bbb.ccc" is from the local IP address
regardless of subnet mask. The number #xx or #x are also valid. The leading 0 is not required (but it's OK).
For example:
• 192.168.0.2 calling 192.168.0.3 -- dial #3 followed by # or “SEND”;
• 192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # “SEND”;
• 192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # “SEND”;
• 192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3.
Note:
• The # will represent colon ":" in direct IP call rather than SEND key as in normal phone call;
• If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will
also use STUN;
• Configure the "User Random Port" to "No" when completing direct IP calls.
ANSWERING PHONE CALLS
RECEIVING CALLS
• Single incoming call. Phone rings with selected ring tone. The corresponding LINE key will flash in
red. Answer call by taking handset off hook, or using Speaker/Headset, or pressing the flashing LINE
key;
• Multiple incoming calls. When another call comes in while having an active call, the phone will
produce a Call Waiting tone (stutter tone). The other LINE key will flash in red. Answer the incoming
call by pressing the flashing LINE key. The current active call will be put on hold automatically.
• Paging/Intercom calls. If the phone has Auto-Answer by Call Info enabled, when there is an incoming
paging/intercom call, the phone will beep once and then automatically establishes the call via
SPEAKER.
