2.1. Wallmount rabbets
2.2. Power jack
2.3. Phone jack

3. Electric wall-plug

The PSTN(2.1.) and POWER (2.2.) connectors are located at the bottom of the Base module(2).

If not using PSTN please connect your IP phone following this hint:

* Connect the ethernet cable delivered in your Gigaset C 455 IP package to the network switch or the wall-plug(3) and insert its free end in the LAN jack(2) on your Gigaset C 455 IP Base module(1).

* Connect your PC to the network switch using another ethernet cable.
* Connect the Internet cable to the network switch .
* Connect the power cable to the Gigaset C 455 IP Base Module and to the appropriate wall-plug.

Now your handset is registered and you can move to the next step – Setup your C 455 IP phone.

Setup

You can setup your IP phone by using the Handset or by using the Web Configuration pages.

As not everyone is used to such menus like the handset's, it is no wonder that the Web Configuring Interface is preferred.

Setting up an Asterisk account

Setting up an Asterisk account to be used with your hardphone.

NOTE: If you are an advanced Asterisk user, please skip the following paragraph about setting up an Asterisk account to use with your phone.

To set up a working SIP account on your Asterisk server, you have to edit some .conf files. Please, connect using your mostly preferred way to your Asterisk server and find where the sip.conf and extensions.conf files are located. They are usually located at the /etc/asterisk/ directory. Now, use your favorite text editor to make some changes. First edit the sip.conf file.
Adding a new user is a simple process, which consists of adding some lines, similar to these in our example here:

I added the following to my sip.conf :

[user]: needed to indicate we are registering user "user".
username=user: to determine our user's name is "user".
context=conf: defines the dial context for the user "user". Asterisk divides outgoing numbers in groups called contexts in order to separate/define different needs for different uses. In this example the user "user" is in a context called "conf".
type=friend: Users that can place AND receive calls are described as "friend". If your new user will only receive calls, use "peer" as type. For placing calls only use "user" as type.
secret=123: this is where you set up your user's password. He will use it to login/authenticate on Asterisk. It is presented in plain text, bus as only the server's administrators (you) have access to this file, there is nothing to worry about.
allow=all: means that the line which this user will use supports all audio codecs.
host=dynamic: You can define your users IP as static or dynamic, according to the type of network.
rfc2833compensate=yes: You must have this turned on, or DTMF reception will work improperly.
nat=yes: If you are placing the phone behind a NAT you must enable that.

Save the changes and continue to register an extension for the user "user" ;).

Now please open the file extensions.conf in your favorite editor to make some changes:

In my file I added :

conf: it is the name of the new context.
The first line "exten => 731,1,Dial(SIP/user)" shows that if somebody dials the number 731 his call will be connected with the user "user" through SIP.
The second line "exten => 731,2,Hangup()" says that if the conversation is over then Asterisk has to hang up the line. It is needed to be sure that Asterisk will free it for the next call.

NOTE: Do not forget to save the changes you just made in extensions.conf .

As your new user "user" is already configured, please start your Asterisk server:

# asterisk

enter the Asterisk CLI console by typing:

# asterisk -r

and reload the SIP configuration for the changes to take effect by using:

# sip reload

then reload the extensions:

# extensions reload

now you can check what you've done by:

# sip show peers

To execute shell command without exiting Asterisk, type "!", then press the [ENTER] key.
Check if there are any sample sounds in your /var/lib/asterisk/sounds/:

#ls /var/lib/asterisk/sounds/

If everything is all right, you will see a long list of files.

I picked up "Hello World.gsm" for this example.

Let us make a new extension in our context.

exten => 111,1,Playback(hello-world) means that if someone from the "conf" context dials 111, he will hear this file played.

Save your extensions.conf file, and press CTRL+D to return to the Asterisk CLI console.
Reload extensions now:

# extensions reload

and exit Asterisk CLI console by typing:

# exit

Now you can dial 111 to test if you will hear the "Hello World" greeting. :)

NOTE: ALL characters after ";" are interpreted by Asterisk as a comment !

ADVICE: read our tutorial about "Configuring IP Phones for use with Asterisk"
for information how to make the configurations in the Asterisk's configuration files.

TESTS

To know that everything is all right you can test it with an echo test, or by installing a softphone.

Echo test

To do an echo test you need to add few more lines in your extensions.conf file.
Open it with your favorite editor and edit it following the example:

exten => 111,1,Answer(): that means that the call will be answered;
exten => 111,2,Echo(): makes possible for you to hear your own voice;
exten => 111,3,HangUp(): hangs up after you've finished the call.

Now, if you dial 111 and say something you will hear your own voice.

Testing by a softphone

To make a test call with a softphone you need one.
Download Zoiper and test it for free from the download section on our website!

Setting an additional account.

Please connect/open a terminal session to your Asterisk server in order to modify your /etc/asterisk/sip.conf file and add one more user account. It will be needed to use with Zoiper.

You can copy the “user” account, and modify it a little.

[user]:change it to [user2] to determine that we are setting an account for “user2”
username=user: change it too -> username=user2to determine our user's name is now "user2".
context=conf: defines the dial context for the user "user2". You should leave it as it is, as “user” and "user2" can be in the same context.
type=friend: leave as it is, as you will need both of your users to place and receive calls when testing.
secret=123: you may use the same password or change it.
allow=all: you do not need to change that.
host=dynamic: you can either enter the IP address of the computer you've just installed Zoiper on or leave this as it is.
rfc2833compensate=yes: You must have this turned on, or DTMF reception will work improperly.
nat=yes: If you are placing the phone behind a NAT you must enable that.

Now save this file and open /etc/extensions.conf to add a new extension for that user.

Setting additional extensions.

You added 3 lines for your first account. Now add the new ones below:

As adding user 2 to the existing context, you do not need to specify a new one.
Just add these two lines:

exten => 732,1,Dial(SIP/user2) shows that if somebody dials the number 732 his call will be connected with the user "user2" through SIP.
exten => 732,2,Hangup(): it is needed to be sure that when the conversation is over then Asterisk has to hang up the line. It is needed to be sure that Asterisk will free it for the next call.

Zoiper Setup

To use your new Zoiper softphone you need an account and you have to set it up.
This you can do following my steps:

Accessing Options Form

Start your Zoiper and right-click on its interface. Click on "Options" to open the configuration menu.

There is an Options button on the Zoiper’s interface. You can start configuration form from there too.

Use "Alt+O" if you prefer using keyboard than clicking.

Adding SIP account

When the form starts you should click on the "Add new SIP account" label in the navigation menu to the left.

A new sub-form will appear. Enter a name the account and click on the "OK" button to create it.
The new entry will appear in the navigation menu to the left.
Click on it to continue the configuration.

On the right side of the navigation menu you can specify some options for the account.
Enter the hostname or the IP address of the Asterisk server (or other VoIP server) that you are going to use.
Enter the account name and secret that you put in the sip.conf file (user2/012). Enter a caller id and name and click on the "Apply" button to activate the changes.

There are additional options that you might want to configure. In order to view the advanced options for the current account you should enable the checkbox with label "Show advanced options" which is located on the bottom left corner.

When you do this you can set an outbound proxy, if necessary, or a voicemail extension, a STUN server, if needed. You can select if Zoiper should register this account upon application’s start-up.

When you are ready click on the "Apply" button.

Registering SIP accounts

You should select the proper account from the drop down menu in the bottom of Zoiper’s interface. When you are ready with this click on the "Register" button.

You can find our Zoiper tutorial here.

As Zoiper supports IAX accounts, you can read the Zoiper tutorial and find out how to set up and use an IAX account.

As you have already set up your hardphone and your softphone, you can make a call from the first to the second one and vice versa :)

Hello, I have some problem with this nice phone. I need to use it in the plant, where is possible only calling of IP address, not number extensions. From C450 I can call IP of all phones, but when I want to call IP of C450, others phones said it is busy. Has anybody the same problem? Would anybody know the solution?

(sorry for my english, I've never been good student)
