VoIP Functionality
This section describes how to use the VoIP function of the DSL router in more detail. Some features involve 2 or 3 parties. In that
case, note that all 3 parties have to be successfully registered.
Registering
Before using any VoIP functions, the DSL router has to register itself to a registrar. The DSL router also has to be configured with a
proxy, which relays VoIP signalling to the next hop. In fact, many implementations integrate these two into one server, so in many
case registrar and proxy refer to the same IP.
1. Select the right interface to use for registering, depending on where proxy/registrar resides. If use WAN link, ensure that it
is already up.
2. Select the checkbox of Use SIP Registrar, and fill in the IP address and port with the right value.
3. Fill the extension information: Authentication name, Password, Cid Name and Cid Number.
4. Click Apply to take the settings into effect.
5. TEL indicator of VoIP service should be on, indicating that SIP client is successfully registered.
Placing a Call
This section describes how to place a basic VoIP call.
1. Pick up the receiver on the phone.
2. Hear the dial-tone. Dial the extension of remote party.
3. To end the dialing, wait for digit timeout, or just press # immediately.
4. After the remote party answers the call, you are in voice connection.
Anonymous call
Anonymous call does not send the caller ID to the remote party. This is useful if you do not want others know whom you are. Check
with your VoIP Provider if your service supports hidden caller ID.
1. Enable Anonymous calling in the Voice--SIP Advanced Setting web page.
2. Pick up the receiver on the phone.
3. Dial *68 to enable anonymous call.
4. Hook on the receiver, and dial another extension as you like. Now your caller ID information is blocked.
Do Not Disturb (DND)
If DND is enabled, all incoming calls are rejected. DND is useful if you do not want others to disturb you. Check with your VoIP
Provider if your service supports DND.
1. Enable DND in the Voice--SIP Advanced Setting web page.
2. Pick up the receiver on the phone.
3. Dial *78 to enable DND.
4. Hook on the phone. Now your phone rejects all incoming calls.
5. Hook off again to disable the DND.
Call Return
For incoming calls, the DSL router remembers the number of calling party. Check with your VoIP Provider if your service supports
Call returns. You cannot call return, if the caller has hidden caller ID.
1. Enable Call Return in the Voice--SIP Advanced Setting web page.
2. Press *69 to return a call.
3. Now you can make the call as if you have dialed the whole number.
Call Hold
Call hold enable you to put a call to a pending state, and pick it up in future. Check with your VoIP Provider if your service supports
Call Hold.
