Ch. 1 Introduction to VoIP

VoIP stands for Voice over Internet Protocol, which means transmitting voice over the most widely accepted network protocol around the world. Internet Protocol networking is widely supported by almost all kinds of networks. VoIP, however, can also be implemented inside LAN only without Internet involved if proper LAN environment is ready. In addition, with improvements, business class VoIP system can integrate data, voice, and video in the same network. This takes simplified management rules into three different systems / networks and results in enhanced performance for all ki nds of organizations.

Later on, this chapter will guide you through the basic elements of the VoIP and some related terms involved as below:

z Advantages of VoIP to Businesses z SIP – Most Popular VoIP Protocol z VoIP-Friendly Networking Concepts

1.1 Advantages of VoIP to Businesses

Telephony system was invented around 100 years ago by Alexander Graham Bell. Though telephones expedite the business communications, it’s expensive especially for international phone calls. Internet Protocol has become the world wide standard. With remarkable improvements in broadband access, VoIP technology and IP Telephony, it is about time to provide businesses high quality IP phone calls at comparably low cost with good reliability. Since voice is transmitted over the Internet there is no demarcation of any physical boundary, this dissolves any need of being charged at very high rate for making international phone calls.

IP Telephony focuses on using your existing telephony resources to build a vibrant communications network that enhances productivity. A common business class VoIP system provides all the features you’ve been familiar with—voicemail, call waiting, call forwarding, to name a few—as well as many new exciting features such as making LOCAL calls at whatever location you may be in the world.

Business world needs reliability and productivity as well. In conventional way, telephony system and computer-based system are two different networks. Hence, the two different networks require normally two times of man-power to manage, and they are hardly managed under a set of unified managing principles. Business class VoIP

system will be able to provide easy-to-manage, business-driven architecture at a cost that is competitive with your current expenditures.

1.2 SIP – Most Popular V oIP Protocol

SIP stands for Session Initiation Protocol which an application-layer is signaling protocol that handles the VoIP phone calls over the Internet. Unlike other VoIP protocols, SIP handles signaling only, and leverages other SIP-related protocols to co-work with media sessions accordingly. The simple and flexible enough architecture brings great chances to SIP for expanding, such as Video phone calls.

Later on, we’ll introduce some terminologies that are common in the VoIP worlds, especially SIP related. In addition, we strongly recommend the system administrator to read other VoIP related documents, textbooks to have better unde rstanding i n orde r to construct a VoIP-friendly network.

1.2.1 SIP Identities

A SIP identity (a.k.a. SIP address or SIP Account) is similar to an email address which is used for identifying who’s who in the SIP world just like email address used for identifying the owner. The format of a SIP identity is like an email address, presented as SIP-Number@SIP-Service-Domain. As the expression shows, there are two major parts in the SIP account; the SIP-Number and SIP-Service-Domain.

z The SIP number is the first part of the SIP URI that is located in front of the “@”

symbol. A SIP number can be alphabet characters just like in an e-mail address (johndoe@ITSP-XYZ.com for example) or numeric digits like a regular telephone number (1234567@ITSP-ABC.com for example).

z The SIP-Service-Domain is the domain name in a SIP URI. It is used to identify who

the service provider is. Normally, it will be the ITSP or the Internet domain name which your company has.

1.2.2 Servers in SIP World

The architecture of SIP protocol is client-server based. Every SIP device or application program will act as SIP client and SIP server as well. The SIP device acts as client when sending out SIP requests, and acts as SIP server once responding to the SIP requests.

The Servers we talk about here aim only at the device, and / or application program which are used to provide VoIP services or application program which is used by

SIP-Service-Domain owner to provide its services to its subscribers. Sometimes, the SIP Registration Server will be used for distinguishing purpose.

There are three kinds of the server:

z SIP Proxy Server; it relays call signaling, i.e. acts as both client and server

operating in a transactional manner, i.e., it keeps no session state

z SIP Redirect Server; it redirects caller to other servers z SIP Registrar; it accepts registration requests from users and maintains user’s

whereabouts at a Location Server.

1.3 VoIP-F riendly Networking Concepts

There are many common features from regular router which will block your VoIP communications, or make your network environment very VoIP-unfriendly. Here are some topics which you need to take care of, or might be helpful in making a VoIP-friendly network.

1.3.1 NAT, Network Address Translation

One of the most common features which router provides in order to provide Internet access to all the computers in your LAN environment is “NAT”. In the simplest case, NAT changes the source IP address of a packet received from a device to another IP address before forwarding the packet towards its destination. When the response comes back, NAT translates the destination address back to the device's IP address and forwards it to the device.

NAT routers are commonly used to translate private (or internal) IP addresses in packet headers to public (or external) IP addresses and vice versa. A NAT router maps a private IP address & port; pairs it to a public IP address & port and whenever the NAT router receives a packet with that public IP address & port, it knows how to reroute the packet back to the private IP address & port.

The WIFI-ATA must know the public IP address which you get from your ISP in order to provide its services. If there is a NAT router between the WIFI-ATA and your broadband modem then your WIFI-ATA probably has a private IP address. In thi s case, the SIP session will not be able to establish properly, and you must configure the NAT router to forward traffic with the correct IP address & SIP port number to solve this problem.

1.3.2 STUN, Simple Traversal of UDP through NAT

STUN can be used to help your, WIFI-ATA, to find the present types of NAT routers and/or firewalls between it and the public Internet. STUN also allows the WIFI-ATA to find the public IP address that NAT has assigned, so that the WIFI-ATA can embed it in the SIP data stream. However, STUN does not work with symmetric NAT routers or firewalls. For more information, please refer to RFC 3489 on STUN.

1.3.3 Voice Codec

A codec (coder/decoder) converts analog voice signals into digital signals and decodes the digital signals back into voice signals. Each codec has its positive part, good voice quality and bad part, bandwidth consumption. WIFI-ATA supports the following codecs.

z ITU-T G.711： G.711 is a Pulse Code Modulation (PCM) waveform codec. G.711

provides very good voice quality but requires 64 K bit/s of bandwidth.

z ITU-T G.729： G.729 is an Analysis-by-Synthesis (ABS) hybrid waveform codec

that uses a filter based information about how the human vocal tract produces sounds. G.729 provides good voice quality and reduces the required bandwidth to 8 K bit/s.

Ch. 2 Introduction to Network application

The WIFI-ATA is an 802.11b/g compatible wireless network device. It can act as the following roles：.

z Bridge z Gateway z WISP z Access Point z AP Client

2.1 Operation Modes

The device provides 3 different operation modes. The operation mode is about the communication mechanism between the wired Ethernet NIC and wireless NIC, the following is the types of operation mode.

z Gateway mode： The wired Ethernet (WAN) port is used to connect with

ADSL/Cable modem and the wireless NIC is used for your private WLAN. The NAT is existed between the 2 NIC and all the wireless clients share the same public IP address through the WAN port to ISP. You can access the web server of device through wireless, the default LAN IP address “192.16 8.1. 254 ” and m odi fy the settin g base on your ISP requirement.

z Bridge mode：The wired E thernet and wi reless NI C are bridged tog ether. Once the

mode is selected, all the WAN related functions will be disabl ed.

z WISP (Wireless ISP) mode：This mo de ca n let you ac cess the AP of your wi rele ss

ISP and share the same public IP address from your ISP to the PCs connecting with the wired Ethernet port of the device. To use this mode, first you must set the wireless radio to be client mode and connect to the AP of your ISP then you can configure the WAN IP configuration to meet your ISP requirement.

2.2 Wireless Modes

The wireless radio of the device acts as t he following roles.

z AP (Access Point)：The wi rele ss radio of device se rves as communications “HUB”

for wireless clients and provides a co nnection to a wi red LAN.

z AP Client：This mode provides the capability to connect with the other AP using

infrastructure/Ad-hoc networking types. With bridge operation mo de, you can directly connect the wired Ethernet port to your PC and the device becomes a wireless adapter. And with WISP operation mode, you can connect the wired Ethernet port to a hub/switch and all the PCs connecting with hub/switch can share the same public IP address from your ISP.

The following table shows the supporting combination of operation and wireless radio modes.
