1.2 How It Works
The following figure shows how the ZyXEL Device works:
• When you make a phone call over the Internet, you use a telephone (A) to dial
the number. The P-2701RL supports one telephone connection, and the P-2702R
supports two telephone connections.
The telephone is connected to your ZyXEL Device (C), which is connected to the
broadband modem or router that provides Internet access (D).
• When you want to use the Internet, you use your computer (B). Your computer
is connected to your ZyXEL Device (C), which is connected to the broadband
modem or router that provides Internet access (D).
You also use your computer to configure the ZyXEL Device.
•P-2701RL Only (E): Use your telephone (A) to make calls over the regular
telephone network (PSTN or Public Switched Telephone Network).

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 10 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 10 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 10 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 21 for more information.
• If you want to dial a SIP number that uses letters or if you want to make a peer-
to-peer call, set up a speed-dial entry first. Use the VoIP > Phone Book >
Speed Dial screen. Then dial the speed-dial number to make the call.
• If you want to call a PSTN phone over the Internet, follow your VoIP provider’s
instructions.

The following table describes the labels in this screen.
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.

Dial Plan
Rules Enter the dial plan rules pattern.
A rules pattern may look something like this:
(*xx|[3469]11|[2-9]xxx|011x)
A dial plan defines the dialing patterns, such as the length and range of
the digits for a telephone number. It also includes country codes, access
codes, area codes, local numbers, long distance numbers or
international call prefixes.
• The collection of rules is in parentheses ().
• Rules are separated by the | (bar) symbol.
• “x” stands for a wildcard and can be any digit from 0 to 9.
• A subset of keys is in a square bracket []. Ranges are allowed.
Without a dial plan, users have to manually enter the whole callee’s
number and wait for the specified dialing interval to time out or press a
terminator key (usually the pound key on the phone keypad) before the
ZyXEL Device makes the call.
