CALL OPERATIONS

Placing a phone call

To make the outgoing calls using your 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.

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 HT802 and other VoIP Device, have public IP addresses, or

Both HT802 and other VoIP Device are on the same LAN using private IP addresses, or

Both HT802 and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).
The 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.
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.
