CALL OPERATIONS

Placing a phone call
To make the outgoing calls using your HT801/HT802:

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.

Notes:
When placing the analog phone that is connected to the FXS port off hook, the dial tone will be played even if the sip account is not registered. If users prefer the busy tone  to be played instead, the following configuration should be made:

• Set “Play Busy Tone When Account is unregistered” to YES under Advanced Settings.
• Set “Outgoing call without registration” to NO under FXS Port (1,2).

Direct IP call
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/HT802 and other VoIP Device, have public IP addresses, or
Both HT801/HT802 and other VoIP Device are on the same LAN using private IP addresses, or
Both HT801/HT802 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).
The HT801/HT802 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.
   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:
a) 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;
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 1921680160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.

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 HT801/HT802 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/HT802 supports Bell core 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/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.
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
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 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.

Inter-Port Calling
In some cases, a user may want to make phone calls between the phones connected to the ports of the same HT802 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 HT802 inter-port calling is achieved by dialing 70X (X is the port number). For example, the user connected to port 1 can be reached by dialing and 701.

Flash Digit Control
If the option “Flash Digit Control” is enabled on web UI, call operation will require different steps as follows:
• Call Hold:
Assume that the call is established between phone A and B.
The phone A received a call from C, then it held B to answer C.
Press the “Flash + 1” to hang up the current call (A – C) and resume call on hold (B). Or press “Flash + 2” to hold current call (A – C) and resume call on hold (B).
• Attended transfer:

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.

3-Way Conferencing:
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.
2. Phone A dials C’s number then # (or wait for 4 seconds).
3. When phone C answers the call, then A can press “Flash +3” to bring B, C in the conference.
   Additional Flash digit events have been added on the latest firmware version 1.0.43.11.
