4The WAN Interface Setting screen has different fields, depending on the type of
Internet access your ISP uses.
You can choose either Static IP,Dynamic IP, or PPPoE:
•Static IP means the ISP has assigned your Internet access account a single
IP address that will never change, regardless of whether you are online or
not. See Section 2.2.1 on page 12 for details.
•Dynamic IP allows the ISP to randomly assign your ZyXEL Device an IP
address each time it requests a WAN (or Internet) session. The IP address is
released as soon as the ZyXEL Device disconnects from the ISP. See Section
2.2.2 on page 12 for details.
•PPPoE emulates a standard dial-up connection over the Internet and requires
that each time the ZyXEL Device requests a WAN session you log in with your
ISP-assigned user name and password. See Section 2.2.3 on page 12 for
details.
Choose the setting required by your ISP then follow the instructions in the
appropriate section below. If you are not sure which setting to use then contact

CHAPTER 3
Phone Use and Configuration
This chapter describes basic phone setup and usage, as well as select advanced
VoIP configuration options for your ZyXEL Device.
3.1 PSTN Phone Set Up (P-2701RL Only)
When one of your VoIP accounts is registered, the ZyXEL Device normally uses the
Internet (VoIP) rather than the regular PSTN phone line to place and receive
phone calls.
However, if you connect the Line port to a regular PSTN phone jack, then
incoming PSTN calls will be forwarded directly to the phone connected to your
ZyXEL Device’s Phone port.
3.2 Placing Phone Calls
Use the following sections to make outgoing calls from a phone attached to the
ZyXEL Device to another phone.
Follow these directions to make calls over the Internet:
• If you want to dial a SIP number that only uses numbers (for example,
“12345”), dial the number on your phone’s keypad. You can also set up a speed-
dial entry, if you want, in the VoIP > Phone Book > Speed Dial screen. See
Section 3.4 on page 24 for more information.
• If you want to make a peer-to-peer call, set up a dial plan with URL entry first.
Use the VoIP > Phone Book > Dial Plan with URL screen. Then dial the pre-
configured SIP number to make the call to a peer VoIP device directly. See
Section 3.5 on page 26 for more information.
• If you want to call a PSTN phone over the Internet, follow your VoIP provider’s
instructions.

Click VoIP > SIP to open the SIP Settings screen. This screen allows you to
manage up to two SIP accounts.
Figure 3 The SIP Settings Screen
To have the ZyXEL Device add a “user=phone” parameter to the SIP URI before
sending a SIP INVITE request, select the Enable option next to Set User Header
To Phone. This parameter indicates the user part of the SIP URI
(<user>@<sipserver>) the ZyXEL Device is calling is a valid telephone number.
If you need to send fax messages using T.38 and want to always use the same
port number for both transmitted and received T.38 packets, select Use Original
RTP Port. Otherwise, select Assign Port for Reinvite to have the ZyXEL Device
choose a port randomly for T.38 after the re-invite process.
Click Apply to save the changes you made in this screen.
Select Active for the phone you want to configure, then click the Modify icon. The
Phone SIP Settings screen opens, where you can set up and maintain your SIP
account(s) in the ZyXEL Device. Your VoIP or Internet service provider should

Table 2 SIP Setting
LABEL DESCRIPTION
SIP Port Enter the port number on your ZyXEL Device that SIP calls made with
the selected phone should use.
Media Port Enter the port number on your ZyXEL Device that RTP media packets
should use.
Packetization Select the voice codec packetization interval in milliseconds. The default
is 20 ms. This is used to minimize loss that happens during
transmission of voice data over the network.
The packetization interval effectivately sets the size of each voice
sample contained within a data packet. At 20 ms, the codec employed
in digitizing the voice signal can usually compensate for data
degredation and attenuation by using Packet Loss Concealment (PLC).
However, if the loss becomes too great, noticeable distortion occurs.
Setting the packetization interval higher, however, may introduce more
problems depending on the codec (such as G.711). Other codecs (such
as G.729 and G.723) have improved PLC techniques and as such can
also withstand a higher packetization interval; this means more packets
can be lost in transit without a noticeable loss in quality.

Figure 6 Advanced SIP Settings (part 2)
DTMF Relay Dual-Tone Multi-Frequency (DTMF) relay detects DTMF signals and
sends them out-of-band (via SIP or RTP) to the remote party. DTMF
relay is used when a low-bitrate voice codec might distort DTMF signals
sent over the voice channel.
The available relay types are:
•RFC2833 - Relays DTMF tones in outband RTP packets.
•SIP INFO - Relays DTMF tones in outband SIP packets.
•PCM - Relays DTMF tones in the voice data stream. PCM provides
very good sound quality with certain codecs (such as G.711) but
requires 64 kbps of bandwidth. With other codecs (such as G.729),
sound distortion may occur.
RFC2833
Payload Type This defines the DTMF tone type in decimal encoding, and which allows gateways to recognize a DTMF tone that has been embedded in a voice
signal and then respond accordingly.
Enter a digit that corresponds directly to a payload event type, as
defined in the RFC-2833 standard.
SIP INFO
Duration (ms) Specify DTMF tone play duration in milliseconds.
Call Waiting Select this to enable the call waiting feature, if supported by your phone
or SIP service provider.
DNS SRV Select Enable to have the ZyXEL Device query your ISP’s DNS server
for a list of any available SIP servers that it maintains. This is useful if
your static SIP server exeriences difficulties, making it hard for your IP
phone users to make SIP calls.
