CALL OPERATIONS

Placing a Phone Call

To make the outgoing calls using your HT812

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