4.6.3 VoIP functionality
This section describes how to use the functionality of 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.
4.6.3.1 Registering
Before using any VoIP functionality, DSL router has to register
itself to a registrar. DSL router also has to be configured with a
proxy, which relays VoIP signaling to next hop. In fact, many
implementations integrate these two into one server, so in
many case registrar and proxy refer to the same IP.
Step 1
Select the right interface to use for registering,
depending on where proxy/registrar resides. If use
WAN link, make sure it is already up.
Step 2
Enter SIP proxy’s IP address or domain name in
SIP
domain name
field. Note if we use domain name, it
must be resolvable to proxy’s IP address.
Step 3
Select the
Use SIP Registrar
check box, and enter the
right value in IP/Port field.
Step 4
Enter the extension information:
Extension

Display

and

.
Authentication Name
and

must be
pre-configured in registrar database.
Step 5
Click
Stop SIP client
(if VoIP application has been
started already), then
Start SIP client
to make above
settings take effect.
Step 6
VoIP LED should be on, indicating that SIP client is
successfully registered.
