User Manual

Introduction

C202  combines the functions of Internet and security with the power of telephony. Using the C202  instead of a traditional adapter, you can connect telephones and reduce your long distance calling costs. It performs the tasks to encode and decode your voice during telephone conversation and sends it over the Internet. The C202  allows you to leverage your investment in High Speed Internet to provide you with high quality, highly featured telephone services at low costs.

Installation

This chapter describes

  1. Installation
  2. Configuring Network Parameters from your Telephone Handset
  3. Configuring Network Parameters from your Web Browser
  1. Locate your C202  close to your Internet connection (High Speed Modem or Ethernet Hub) and a power outlet.
  2. Using RJ-45 connector of the Ethernet 10/100Base-T cable to connect LAN port with internet.
  3. Plug one end of the RJ-11 of phone cord to the RXS port of the C202 , plug the other end into your telephone or a PABX port.
  4. Plug the accessory power-adapter into the power outlet, then connect the output-plug to power-port of the C202 .
  5. The C202  will now boot up and log into the service.

NOTE: 
You may need to select different RJ-45 cables depending on what you are connecting the C202  to. In most cases you should use a “Straight Through” cable, there may be some setups where you will need a “Cross Over” cable.
Please refer to connection chart in the appendix for further information.

Configuration

Configuring Network Parameters from Your Web Browser

At anytime and under any mode, you can always manage your C202  via the internet and your Web Browser (standard web browser support), from any computer operating system.

When the boot process is complete, connect your PC to the LAN port of C202 .

There are two modes to enter C202  User Interfaces

Mode 1: You can pick up the handset and continually press * four times (****) to enter the “Interactive Voice Response” (IVR) service. After you hear the voice prompt, press 100* and record the IP address that will be spoken to you.
If C202  and PC are located on the same network, open an Internet browser on the PC, then type the IP address into the address bar and press Enter to enter the login page. The default values are; account: user, password: voip (Please note differentiating uppercase and lowercase)

Mode 2:
Connect the LAN port of C202  to PC, and press the Reset button on your C202 . Change the network settings of your PC to IP: 192.168.20.100, Subnet mask: 255.255.255.0, gateway IP: 192.168.20.1. Then type the default IP address http://192.168.20.1 into the address bar and press Enter to enter the login page.

Once logged in you can make changes (if necessary) to the network or SIP settings.

If not chosen the above codes will not operate properly. Do the following steps to set the function of #: open C202  settings page>SIP>Server>Gateway settings> ‘use # as a quick dial function’ option

NOTE: 
If you go on pressing the Reset button on C202  when plug in the power, after the boot process is complete, the IP address and subnet mask IP are changed to 192.168.20.1 and 255.255.255.0 respectively.

Appendix II

Dial Plans

The H.323 and SIP code will allow provisioning (via web browser) of the dial plan. A dial plan gives the unit a map to determine when a complete number has been entered and should be passed to the gatekeeper for resolution into an IP address. Dial plans are expressed using the same syntax as used by MGCP NCS specification.
The formal syntax of the dial plan is described by the following notation:
Digit ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Timer ::= "T" | "t"
Letter ::= Digit | Timer | "#" | "*" | "A" | "a" | "B" | "b" | "C" | "c"| "D" | "d"
Range ::= "X" | "x" -- matches any digit
| "[" Letters "]" -- matches any of the specified letters
Letters::= Subrange | Subrange Letters
Subrange::= Letter -- matches the specified letter
| Digit "-" Digit -- matches any digit between first and last
Position::= Letter | Range
StringElement::= Position -- matches any occurrence of the position
| Position "." -- matches an arbitrary number of occurrences
including 0
String ::= StringElement | StringElement String
StringList::= String | String "|" StringList
DialPlan::= String | "(" StringList ")"
A dial plan, according to this syntax, is defined either by a (case insensitive) string or by a list of strings. Regardless of the above syntax a timer is only allowed if it appears in the last position in a string (12T3 is not valid). Each string is an alternate numbering scheme. The unit will process the dial plan by comparing the current dial string against the dial plan, if the result is unqualified (partial matches at least one entry) then it will do nothing further. If the result matches or is over-qualified (no further digits could possibly produce a match) then send the string to the gatekeeper and clear the dial string. The Timer T is activated when it is all that is required to produce a match. The period of timer T is 4 seconds. For example a dial plan of (xxxT|xxxxx) will match immediately if 5 digits are entered, it will also match after a 4 second pause when 3 digits are entered.


Sample Dial Plans

Simple Dial Plan
Allows dialing of 7 digit numbers (e.g. 5551234) or an operator on 0. Dial plan is (0T|xxxxxxx)
Non-dialed Line Dial Plan
As soon as handset is lifted the unit contacts the gatekeeper (used for systems where dtmf detection is done in-call). Dial plan is (x.) i.e. match against 0 (or more) digits. Note: the dot ‘.’
Complex Dial Plan
Local operator on 0, long distance operator on 00, four digit local extension number starting with 3,4 or 5, seven digit local numbers are prefixed by an 8, two digit star services (e.g. 69), ten digit long distance prefixed by 91, and international numbers starting with 9011+variable number of digits.
Dial plan for this is:

(0T|00T|[3-5]xxx|8xxxxxxx|*xx|91xxxxxxxxxx|9011x.T
