Benefits

Support Multiple SIP Phone Numbers and Automatic Number Assignment Mechanism
End users can use 4 phone lines simultaneously. The P-2304R-P1 automatically uses one of the phone ports for communication. With support of G.729 on each phone port, the P-2304R-P1 is ideal in a network environment with limited bandwidth.
Integrated NAT Router Capability
The Network Address Translation (NAT) feature on the P-2304R-P1 allows multiple computers on the LAN to share a single Internet connection. This eliminates purchases of additional network routing devices and provides an affordable and easy-to-use Internet sharing experience.

Rich Call Features

The P-2304R-P1 comes with a comprehensive set of phone features such as the built-in phone book. In addition, the keypad allows users to forward calls, transfer calls, perform three-way call conferencing, etc.
Effective Network Bandwidth Management and State-of-theart Security Firewall
The P-2304R-P1 enables network administrators to allocate network resources while guaranteeing Quality of Service (QoS). Network Bandwidth Management increases productivity and efficiency by tailoring a system to specific demands such as time-sensitive VoIP and multimedia applications. In addition, the ICSAcertified ZyNOS operating system ensures state-of-the-art SPI firewall protection especially against DoS attacks. Thus the P-2304R-P1 provides the first line of defense against hackers, network intruders, and other malicious threats.
Easy Provisioning Management with TR-104 (customizable)
The TR-104 Provisioning parameter for VoIP CPE defines the data model for provisioning of a VoIP CPE device by an Auto-configuration Server (ACS) using the mechanism. With TR-104 support, service providers can easily manage and configure the P-2304R-P1 remotely using an ACS server.

CHAPTER

1.1 VoIP Station Gateway Overview
Introducing the ZyXEL Device
This chapter introduces the main features and applications of the ZyXEL Device.
The P-2304R-P1 VoIP (Voice over IP) station gateway lets you use traditional analog telephones to make telephone calls over the Internet. The ZyXEL Device uses SIP (Session Initiation Protocol), an internationally recognized standard for implementing VoIP. You can call any landline or mobile telephone as well as IP telephones. You dont need to know if the recipients connection type is an IP, cellular or landline based service. Calls received from IP telephones work exactly as you would expect from the traditional telephone service. The NAT and DHCP server features allow you to use an Ethernet hub or switch to set up a private network and allow multiple computers to share a single Internet connection. The ZyXEL Device also provides content filtering and a firewall for security. The ZyXEL Device's web configurator allows easy management and configuration. See Appendix A on page 223 for a complete list of features.
1.2 Ways to Manage the ZyXEL Device
Use any of the following methods to manage the ZyXEL Device. Web Configurator. This is recommended for everyday management of the ZyXEL Device using a (supported) web browser. Command Line Interface. Line commands are mostly used for troubleshooting by service engineers. FTP for firmware upgrades and configuration backup/restore. SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this Users Guide.
1.3 Good Habits for Managing the ZyXEL Device
Do the following things regularly to make the ZyXEL Device more secure and to manage the ZyXEL Device more effectively.
Chapter 1 Introducing the ZyXEL Device
Change the password. Use a password thats not easy to guess and that consists of different types of characters, such as numbers and letters. Write down the password and put it in a safe place. Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the ZyXEL Device. You could simply restore your last configuration.

Use the ZyXEL Device to make a call to the recipients IP address without using a SIP proxy server. Peer-to-peer calls are also called Point to Point or IP-to-IP calls. You must know the peers IP address in order to do this. The following figure shows a basic example of how you would make a peer-to-peer VoIP call. You use your analog phone (A in the figure) and the ZyXEL Device (B) changes the call into VoIP. The ZyXEL Device then sends your call through the Internet to the peer VoIP device (C).
Figure 4 Peer-to-peer Calling
Introducing the Web Configurator
This chapter describes how to access the ZyXEL Device web configurator and provides an overview of its screens.
2.1 Web Configurator Overview
The web configurator is an HTML-based management interface that allows easy ZyXEL Device setup and management via Internet browser. Use Internet Explorer 6.0 and later or Netscape Navigator 7.0 and later versions. The recommended screen resolution is 1024 by 768 pixels. In order to use the web configurator you need to allow: Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in Windows XP SP (Service Pack) 2. JavaScripts (enabled by default). Java permissions (enabled by default). See the troubleshooting chapter if you want to make sure these functions are allowed in Internet Explorer or Netscape Navigator.
2.2 Accessing the Web Configurator
1 Make sure your ZyXEL Device hardware is properly connected and prepare your computer/computer network to connect to the ZyXEL Device (refer to the Quick Start Guide). 2 Launch your web browser. 3 Type "192.168.1.1" (the ZyXEL Devices default LAN IP address) as the URL. The Login screen appears.

4.4 Bandwidth Management Wizard
Use this wizard to control how much traffic can pass through your ZyXEL Device and the priority of each service (application) that can use it. Each service you select is guaranteed a small amount of bandwidth. The remaining bandwidth is divided by priority. If one service has higher priority than another, then the first service uses as much of the remaining bandwidth as it needs. If there is no more bandwidth for the second service, then it waits. If you do not select a service in this wizard (or if you do not find a particular service), the service can still use bandwidth, but it does not have any guaranteed amount and it has the lowest priority. See Chapter 15 on page 153 for more information.

LABEL Active Managed Bandwidth (kbps) DESCRIPTION Select this to enable bandwidth management. Bandwidth management applies to all traffic flowing through the router. Enter the total amount of traffic the device can send to the WAN. It is recommended to set this speed to what the device connected to the WAN can handle. For example, set this field to 1000 kbps if a broadband device connected to the WAN port has a maximum speed of 1000 kbps. This does not affect the total amount of traffic the device can send to the LAN. See Management > Bandwidth MGMT > Summary to do this. Click this to go to the previous screen. Click this to go to the next screen. Click this to close this screen and return to the main screen.

The ZyXEL Device supports DTMF at the time of writing. The ZyXEL Device does not support DiffServ at the time of writing.
Chapter 9 SIP Figure 58 DiffServ: Differentiated Service Field
DSCP (6-bit) Unused (2-bit)
DSCP is backward compatible with the three precedence bits in the ToS octet so that nonDiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies. 9.1.11.4 VLAN Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Only stations within the same group can communicate with each other. Your ZyXEL Device can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the ZyXEL Device to communicate with a SIP server that is a member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other traffic.

9.2 SIP Screens

9.2.1 SIP Settings Screen
Use this screen to maintain basic information about each SIP account. Your VoIP service provider (the company that lets you make phone calls over the Internet) should provide this. You can also enable and disable each SIP account. To access this screen, click VoIP > SIP > SIP Settings.

LABEL SIP Account SIP Server Settings URL Type Select whether or not to include the SIP service domain name when the ZyXEL Device sends the SIP number. SIP - include the SIP service domain name TEL - do not include the SIP service domain name Enter the number of seconds your SIP account is registered with the SIP register server before it is deleted. The ZyXEL Device automatically tries to re-register your SIP account when one-half of this time has passed. (The SIP register server might have a different expiration.) Enter the number of seconds the ZyXEL Device waits before it tries again to register the SIP account, if the first try failed or if there is no response. Enter the number of seconds the conversation can last before the call is automatically disconnected. Usually, when one-half of this time has passed, the ZyXEL Device or the other party updates this timer to prevent this from happening. Enter the minimum number of seconds the ZyXEL Device accepts for a session expiration time when it receives a request to start a SIP session. If the request has a shorter time, the ZyXEL Device rejects it. Enter the listening port number(s) for RTP traffic, if your VoIP service provider gave you this information. Otherwise, keep the default values. To enter one port number, enter the port number in the Start Port and End Port fields. To enter a range of ports, enter the port number at the beginning of the range in the Start Port field enter the port number at the end of the range in the End Port field. Select the type of voice coder/decoder (codec) that you want the ZyXEL Device to use. G.711 provides higher voice quality but requires more bandwidth (64 kbps). G.711A is typically used in Europe. G.711u is typically used in North America and Japan. In contrast, G.729 only requires 8 kbps. The ZyXEL Device must use the same codec as the peer. When two SIP devices start a SIP session, they must agree on a codec. Select the ZyXEL Devices first choice for voice coder/decoder. DESCRIPTION This field displays the SIP account you see in this screen.

Scheduler Maximize Bandwidth Usage

WAN Active

Chapter 15 Bandwidth MGMT Table 70 Management > Bandwidth MGMT > Summary
LABEL Speed DESCRIPTION Enter the amount of bandwidth for this interface that you want to allocate using bandwidth management. The recommendation is to set this speed to match the interfaces actual transmission speed. For example, set the WAN interface speed to 1000 kbps if your Internet connection has an upstream transmission speed of 1 Mbps. You can set this number higher than the interfaces actual transmission speed. This will stop lower priority traffic from being sent if higher priority traffic uses all of the actual bandwidth. You can also set this number lower than the interfaces actual transmission speed. If you do not enable Max Bandwidth Usage, this will cause the ZyXEL Device to not use some of the interfaces available bandwidth. This field is not affected by the Bandwidth Management Wizard. Select Priority-Based to give preference to bandwidth classes with higher priorities. Select Fairness-Based to treat all bandwidth classes equally. Select this if you want the ZyXEL Device to divide any unallocated and unused bandwidth among bandwidth classes that require bandwidth. Clear this if you want to reserve bandwidth for traffic that does not match a bandwidth class or if you want to limit the speed of this interface. Click this to save your changes and to apply them to the ZyXEL Device. Click this to set every field in this screen to its last-saved value.
15.2.2 Bandwidth Class Setup Screen
Use this screen to look at the configured bandwidth classes by individual interface. Each interface has a permanent root class. The bandwidth budget of the root class is equal to the speed you configured on the interface (see Section 15.2.1 on page 158). There is a default class for all the bandwidth in the Root Class that is not allocated to bandwidth classes.
For each interface, you must enable bandwidth management before you can configure classes.

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.

NAT Definitions

Inside/outside denotes where a host is located relative to the ZyXEL Device. For example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/local denotes the IP address of a host in a packet as the packet traverses a router. For example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note that inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information.
Table 125 NAT Definitions
TERM Inside Outside Local Global DESCRIPTION This refers to the host on the LAN. This refers to the host on the WAN. This refers to the packet address (source or destination) as the packet travels on the LAN. This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT never changes the IP address (either local or global) of an outside host.

Appendix F NAT

What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed. The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers (for example a web server and a telnet server) on your local network and make them accessible to the outside world. If you do not define any servers (for Many-to-One and Many-to-Many Overload mapping), NAT offers the additional benefit of firewall protection. With no servers defined, your ZyXEL Device filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
