1. Introduction
The D-Link DVG-2001S VoIP Terminal Adapter links traditional telephony networks to
IP networks with conventional telephony devices such as analog phones or fax
machines. It can reduce long distance phone charges and deliver toll-quality voice
communication over the IP network. This gateway provides one loop start Foreign
Exchange Subscriber (FXS) port and one Ethernet port.

for Cable modem services.
The Host Name is optional but may be required by some ISPs. The
default host name is the device name of the VoIP TerminalAdapter and
may be changed.
The default MAC Address is set to the WAN’s physical interface MAC
address on the VoIP Terminal Adapter. It is not recommended that you
change the default MAC address unless required by your ISP.

The VoIP Terminal Adapter can be
configured to handle voice signals
over the Internet Protocol (Voice
Over IP −VOIP). The screen
shown to the right, along with
those on the following pages are
used to configure your router to
communicate with the devices
that will send and receive
telephone calls over the Internet.
Use this drop-down menu to Enable or Disable the Server Fully Qualified
Domain Name (FQDN) function. This is disabled when the SIP URL domain
name is different from the SIP proxy server domain name. The phone will
then use the domain name in Domain Name field as part of SIP URL but
send and receive SIP messages through the SIP proxy server defined in the
Service Domain field.
Enter the IP address of the SIP Server in this field.
Enter the domain name corresponding to the IP address entered above in
this field.
Enter the SIP server’s listening port for the SIP in this field. Leave this field
set to the default if your VoIP service provider did not give you a server port
number for SIP.
Enter the SIP service domain name in this field.
Select SIP-URL to have the router include the domain name with the SIP
number in the SIP messages that it sends. Select TEL-URL to have the
router use the SIP number without a domain name in the SIP messages that
it sends.
You can set this to Enabled or Disabled. This determines whether or
not the phone number is appended to the information forwarded to
your SIP server. Your VoIP service provider will instruct you on which
setting to use.

You can set this to YES or NO. This determines whether CID is received.
You can set this to Enabled or Disabled. This determines whether to
display Caller ID.
Use the drop-down menu provided to select the desired time increment.
You can set this to Enabled or Disabled. The default is Enabled.
Use this field to set how long the router will wait before sending a repeat
registration request if a registration attempt fails or there is no response
from the registration server.
This field will set the longest time that the router will allow a SIP session to
remain idle (without traffic) before dropping it.
When two SIP devices negotiate a SIP session, they must negotiate a
common expiration time for idle SIP sessions. This field sets the shortest
expiration time that the router will accept. The router checks the session
expiration values of incoming SIP INVITE requests against the minimum
session expiration value that you enter here. If the session expiration of an
incoming INVITE request is less than this value, the router negotiates with
the other SIP device to increase the session expiration value to match the
minimum session expiration value.
This determines which side of an expired call session will initiate
the session refresh. uac – specifies the Caller side will initiate the
session refresh. uas – specifies the Call receiver (the “Callee”) will
initiate the session refresh..

F. Advanced > VOIP > STUN Configuration
STUN is useful if you need to use the DVG-2001S behind a modem or router that
provides the connection to your ISP and then to the Internet and does not support
symetric NAT. You will need access to a STUN server on the Internet and its IP
address to use STUN on the DVG-2001S.

STUN NAT Type
Simple Traversal of UDP over NAT
(STUN) −is a protocol that enables
a VoIP device, such as this router
or an IP phone, to detect the
presence and type of NAT behind
which the phone is placed. This
router supports STUN and can
intelligently modify the private IP
address and port in its SIP/SDP
message by using the NAT mapped
public IP address and port through
a series of STUN queries against a
STUN server located on the public
Internet. This will allow SIP
signaling and RTP media to
successfully traverse a NAT without
requiring any configuration
changes on the NAT.
Use this drop-down menu to Enable or Disable STUN on the router.
Enter the IP address of a STUN server in this field.
Enter the port number the STUN server will use in this field. If you do not
have any information as to the proper port number, leave the default setting
here.
This determines the amount of time, in seconds, between STUN requests.
If you do not have any information as to the proper interval, leave the
default setting here.

Out-of band Dual Tone Multi-frequency – The Dual Tone Multi-frequency
(DTMF) mode sets how the router will handle the tones that your telephone
makes when you push its buttons. It is recommended that you use the
same mode that your VoIP service provider uses. Select Enabled (RFC
2833) to send the DTMF tones in RTP packets. Select Disabled (G.711) to
include the DTMF tones in the voice date stream. This method works best
when you are using a codec that does not use compression (like G.711).
The payload type (PT) field identifies the format of the RTP payload and
determines its interpretation by the receiving application
