Overview of the M22

The M22 Professional IP phone is an easy-to-use high quality desk phone with many advanced features. Utilizing a next generation capacitive touch sensitivity panel design, the M22 supports up to four simultaneous lines and can be positioned in multiple tilt angles and has a wall mount option, and has a built-in t wo port 10/100 Ethernet switch with automatic support for power over Ethernet (PoE). The M22 has 8 programmable buttons and can be configured through the simple built in menus displayed on the blue backlit LCD or from the phone’s web user interface. The M22 can be automatically provisioned from a local or Internet based on IG servers.
The M22 IP Phone supports many advanced features including 5-way on-phone conferencing, can transfer and receive calls using industry-standard SIP protocols, and can provide built-in music-on-hold (MoH) over IP network. Therefore, the M22 can be deployed and used anywhere there is a suitable local area network (LAN) with Internet access and a local or remotely hosted SIP server. Since it is a stand-alone and “always-on” device, it does not require connection to a computer for it to work.
In addition, the M22 has a large LCD display to show all calls in progress at once and supports HD audio through the use of the G.722 wideband codec, has a dedicated external headset port, and an Extended Dial Module port. These functions make the M22 a more powerful and flexible IP phone to meet the demands of a busy professional user.

The Front-View of the M22

The M22 Standard IP Phone comes with a blue backlit L CD display, capacitive touch keys, including 4 soft keys, 3 line keys, and 5 navigator keys, as well as a traditional keypad, 8

General Operations

Introduction

To operate the M22, you need to know some conventions that we will mention in this manual. In the following descriptions, we will introduce some terminologies for your understanding.

Calls

A “Call” in this guide represents how many simultaneous connecti ons can be made to a single phone number. M22 has only one line based on IG server, which can support up to four calls simultaneously. This allows the user to place one caller on hold and talk to the other person in another call on the same Line. Therefore, the M22 phone is said to support multiple call appearances.

Register to IG7600

The M22 supports Plug-n-Play function to register and get configured automatically when it is connected to IG7600’s LAN/WAN port (with same subnet as IG7600). It also supports manual configuration if it is a remote phone (need to obtain the account information from system administrator).
Refer to Configuration through Menus or Configuration through Web for detail inform at ion of how to configure the phone to register to IG7600.

Caller ID & User ID

When you receive a call, the caller's phone number is shown on the screen, if the caller hasn’t chosen to hide his number and if the network supports the Caller ID feature. The IP Phone can display both the Caller ID (CLID) and the Caller Name (CNAM) of the caller if it is available. Not all services and servers support CLID and CNAM. For more information about this topic, please contact your service provider or system administrator.

Using Multiple Calls

Each line of service in the M22 can support up to four calls simultaneously. It allows you to place one caller on hold and talk to the other person in another call on the same line.
26
Page 27
M22 USER MANUAL
For example, the following screen shows you line 220 has one active call with number 240. When you dial the number 240, the number you dial will show on the LCD.
When the call party answers the call, the LCD will show as below.
Press the Hold key to keep this call.
You can make a new call on the same line by pressing NewCl.
27
Page 28
M22 USER MANUAL
After the called party answers the call, the following screen shows you line has two calls, the call to number 240 is on hold, and the call to number 245 is active.
By the steps as above, you can use one line to make 4 calls simultaneously.

10/100BASE-T
It’s a LAN transmission line specification s tipulated by IEEE. Transmission speed is 10 or 100 Mbps and the modulation technique is base
modulation. The cable uses unshielded twisted pair, similar to a telephone wire. 10BaseT is an IEEE standard (802.3) for operating 10 Mbps Ethernet networks (LANs) with twisted pair cabling and a wiring hub.
Auto answer
In telephone call control: The capability of a machine to answer a ringing telephone without human intervention.
CODEC
The CODEC (CODER/DECODER) is a standard through which voice information can be encoded into data or decoded back to voice informat ion. Both a Coder and Decoder are necessary on both sides of the telephone call since telephone calls occur simultaneously in both directions. Bandwidth is an extremely important factor in QOS (Quality of Service). MOS (Mean Opinion Score) is an attempt to make a quantifiable benchmark of voice quality. Below are examples of the CODEC, bit rate and mean opinion score: G.711 (toll quality) 64K MOS=4.1, G.726 16K (32K) MOS =3.8, G

IP address
A 32-bit number that identifies each sender or receiver of information that is sent across the Internet. An IP address has two parts: an identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. A number used to identify the location of a host device. It is expressed in numeric dot notation (e.
MAC address
Media Access Control address (MAC address): It is a unique identifier assigned to most network adapters or network interface cards by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. It may also be known as an Ethernet Hardware Address or physical address. In TCP/IP networks, the MAC address of a subnet interface can be queried with the IP address using the Address Resolution Protocol (ARP) for Internet Protocol. On broadcast networks, such as Ethernet, the MAC address uniquely identifies each node and allows frames to be marked for specific hosts. It thus forms the basis of most of the Link layer (OSI Layer 2) networking upon which upper layer protocols rely to produce complex,
NAT
Network Address Translation
: A network capability that enables a houseful of computers to dynamically share a single incoming IP address from a dial-up, cable or xDSL connection. NAT takes the single incoming IP address and creates new IP address for each client computer on the network.
Proxy server
Used in larger companies and organizations to improve network operations and security, a proxy server is able to prevent direct communication between two or more networks. The proxy server forwards allowable data requests to remote servers and/or responds to data requests directly from stored remote server data.
PSTN
Public Switched Telephone Network

SIP
Session Initiation Protocol
: A protocol that provides telephony services similar to H.323, but is less complex and uses fewer resources. SIP is a signaling protocol for Internet conferencing, telephony, presence, events notification and instant messaging. SIP is a text-based protocol, similar to HTTP and SMTP, for initiating interactive commun

TCP/IP
Internet Standard Protocol: The underlying technology behind the Internet and communications between computers in a network. The first part, TCP, is the transport part, which matches the size of the messages on either end and guarantees that the correct message has been received. The IP part is the user's computer address on a network. Every computer in a T CP / IP network has its own IP address that is either dy namically ass igned at sta rtup or perma nently as signed.

All TCP/IP messages contain the addres s of the destination network as w ell as the address of the destination station. This enables TCP/IP messages to be transmitted to multiple networks (subnets) withi n an organization or worldwide.
VAD
Voice Activity Detection (VAD) helps save bandwidth during calls. Examples: When
listening, that silence is still taking up bandwidth during the call. When silence is detected by VAD software over a predetermined length of time, it sends silent packets that inform other VAD enabled systems to stop holding the bandwidth for these empty packets.
VoIP
Voice Over Internet Protocol: VoIP is based on the principal of transmitting digitized voice packets over networks. Basically, VoIP consists of converting voic e signals into streams of digital packets and sending those packets of data through an IP-constructed network environment. VoIP can work in both LAN (local area network) and WAN (wide area network) environments for internetwork or internetwork communication between VoIP channel users. Routers and switches and other special compression protocols direct the packetized voice data to their destination IP address. VoIP can be less expensive than voice transmission using standard analog packets over POTS (Plain Old Telephone Service). It allows telephone calls, faxes, or overhead paging to be transported over an existing IP data network topology.
