CALL OPERATIONS

Placing a Phone Call
To make the outgoing calls using your HT812/HT814

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

   VoIP service provider for further details on prefix numbers.

Note:
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 need to be made:

• “Play Busy Tone When Account is unregistered” need to be set to YES under advanced
  settings.

• “Outgoing call without registration” need to be set to NO under Profile x settings.
  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 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.

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:

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.

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
