• Both HT812/HT814 and other VoIP Device, have public IP addresses, or
• Both HT812/HT814 and other VoIP Device are on the same LAN using private IP addresses, or
• Both HT812/HT814 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).

The HT812/HT814 support two ways to make Direct IP Calling:

Using IVR

1. Pick up the analog phone then access the voice menu prompt by dialing “***”
2. Dial “47” to access the direct IP call menu
3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling”

Using Star Code

1. Pick up the analog phone then dial “*47”
2. Enter the target IP address.

No dial tone will be played between step 1 and 2 and destination ports can be specified using “*” (encoding for “:”) followed by the port number.

Examples of Direct IP Calls:

• If the target IP address is 192.168.0.160, the dialing convention is 47 or Voice Prompt with option 47, then 1921680160, 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
• 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 1921680160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.

When completing direct IP call, the “Use Random SIP/RTP Port” should set to “NO”.

Call Hold

• You can 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

• The call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled.
• To toggle between incoming call and current call, you need to press the “flash” button the first call is placed on hold.
• Press the “flash” button to toggle between the active calls.

Call Transfer

Blind Transfer
Assume that the call is established between phone A and B are in conversation. The phone A wants to blind transfer phone B to phone C:

1. On the phone A presses FLASH to hear the dial tone.
2. The phone A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds)
3.  The phone A will hear the dial tone. Then, A can hang up.

“Enable Call Feature” must be set to “Yes” in web configuration page.
Attended Transfer
Assume that the call is established between phone A and B are in conversation. The phone A wants to attend transfer phone B to phone C:

1. On the phone A presses FLASH to hear the dial tone.
2. Phone A dials the phone C’s number followed by # (or wait for 4 seconds).
3. If phone C answers the call, phones A and C are in conversation. Then A can hang up to complete transfer.
4. If phone C does not answer the call, phone A can press “flash” to resume call with phone B.

When attended transfer fails and A hangs up, the HT812/HT814 will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B.

3-Way conferencing
The HT812/HT814 support Bellcore style 3-way Conference. To perform the 3-way conference, we assume that the call is established between phone A and B are in conversation. Phone A(HT812/HT814) wants to bring third phone C into conference:

1.  Phone A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
2. Phone A dials C’s number then # (or wait for 4 seconds).
3. If phone C answers the call, then A presses FLASH to bring B, C in the conference.
4. If phone C does not answer the call, phone A can press FLASH back to talk to phone B.
5. If phone A presses FLASH during conference, the phone C will be dropped out.
6. If phone A hangs up, the conference will be terminated for all three parties when configuration “Transfer on Conference Hang up” is set to “No”. If the configuration is set to “Yes”, A will transfer B to C so that B and C can continue the conversation.

Call Return
In order to call back to the latest incoming number.

1. Pick up the handset of the connected phone (Off-hook).
2. After hearing the dial tone, input “*69”.
3. Your phone will automatically call back to the latest incoming number.

All star codes (*XX) related features mentioned above are supported by ATA default settings. If your service provider provides different feature codes, please contact them for instructions.

Inter-Port Calling

• In some cases, a user may want to make phone calls between the phones connected to multiple ports of the same HT81x when it is used as a standalone unit, without the use of a
• SIP server. In such cases, users still will be able to make inter-port calls by using the IVR feature.
• On the HT81x inter-port calling is achieved by dialing 7X (X is the port number). For example, the user connected to port 1 can be reached by dialing and 71.

• Or press “Flash + 2” to hold current call (A – C) and resume call on hold (B).

Assume that the call is established between phone A and B. The phone A wants to attend transfer phone B to phone C:

1. On the phone A presses FLASH to hear the dial tone.
2. Phone A dials the phone C’s number followed by # (or wait for 4 seconds).
3. If phone C answers the call, phones A and C are in conversation. Then A can press “Flash + 4” to complete transfer.

Assume that the call is established, and phone A and B are in conversation. Phone A(HT801/HT802) wants to bring third phone C into conference:

1. Phone A presses Flash (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
