CONFIGURATION GUIDE

The HT801 can be configured via one of two ways:

• The IVR voice prompt menu.
• The Web GUI embedded on the HT801 using PC's web browser.

Obtain HT801 IP Address via Connected Analogue Phone

HT801 is by default configured to obtain the IP address from DHCP server where the unit is located. In order to know which IP address is assigned to your HT801, you should access to the "Interactive Voice Response Menu" of your adapter via the connected phone and check its IP address mode.

Please refer to the steps below to access the interactive voice response menu:

1. Use a telephone connected to phone port of your HT801.
2. Press *** (press the star key three times) to access the IVR menu and wait until you hear "Enter the menu option ".
3. Press 02 and the current IP address will be announced.

Understanding HT801 Interactive Voice Prompt Response Menu

The HT801 has a built-in voice prompt menu for simple device configuration which lists actions, commands, menu choices, and descriptions. The IVR menu work with any phone connected to the HT801. Pick up the handset and dial "***" to use the IVR menu.

Five success tips when using the voice prompt

• "*" shifts down to the next menu option and "#" returns to the main menu.
• "9" functions as the ENTER key in many cases to confirm or toggle an option.
• All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26 should be key in like 192168000026. No decimal is needed).
• Key entry cannot be deleted but the phone may prompt error once it is detected.

CALL OPERATIONS

Placing a phone call

To make the outgoing calls using your HT801

1. Pick up the handset of the connected phone;
2. Dial the number directly and wait for 4 seconds (Default "No Key Entry Timeout"); or
3. Dial the number directly and press # (Use # as dial key" must be configured in web configuration).

Examples:

1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds;
2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

Direct IP calls

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.

Elements necessary to completing a Direct IP Call:

• Both HT801 and other VoIP Device, have public IP addresses, or
• Both HT801 and other VoIP Device are on the same LAN using private IP addresses, or
• Both HT801 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).

The HT801 supports 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.

Note: 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:

1. 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;
2. 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 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.

Note: "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.

Note: When attended transfer fails and A hangs up, the HT801 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 HT801 supports 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(HT801) 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", and follow by "#" or wait for time out.
3. Your phone will automatically call back to the latest incoming number.

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