Two steps are required in order to use an external link, and two other steps are optional:

Creation of a VoIP Account
Creation of an incoming line (optional)
Creation of an outgoing line (optional)
Update of the appropriate Class of Service (CoS)

Creation of the VoIP Account

In the Telephony -> Interface menu , in the VoIP Account TAB, click on ‘Add New VoIP Account ‘

General Tab:  Create a SIP trunk type Ami. name the instance B2B2C.
Server Tab:     Specify the server address in the box B2B2C Host / IP, the host mode is set to specific. If you have a username and password, specify it. Register as a user agent is optional.
Network Tab: Check boxes: Trunk behind a Nat, Unsecure Port and Invites (required for incoming calls), and Qualifier
Options Tab:  Automatic Mode DTMF (RFC2833/Inband)

Save configuration.

Creation of incoming line

In the menu Telephony –> Lines, incoming line Tab, click  ‘Add a new line’

General tab: Type Post (DNIS), Indicate in the box Post the phone number assigned to you.
Destination tab: Select the desired destination, such a position.
Options tab: Select the trunk created in the previous step, in this case B2B2C.

Save configuration.

Creation of an outgoing line

In the menu Telephony –> Lines,  outgoing line Tab, click  ‘Add a new line ‘

General tab: Name your line, for example B2B2C B2B2C and enter the trunk.
Dial String tab: Simply put in first, choose a custom dial string and enter ‘X’. This configuration is not adequate but to validate the operation.
Caller ID tab: Click Force the outgoing caller ID, and specify your main phone number and the name of the company. This is mandatory.

Save configuration

Update the Class of Service (CoS)

In the menu Telephony –> Manager, Class of Service Tab, choose the Class of Service where you have defined your internal extensions.

Outgoing Lines tab:  Either you check the ‘Allow all outgoing lines’ or you include the B2B2C line in the list authorized lines.

Save configuration

 

NOTE: You need to register every 3600 seconds with this supplier. This parameter can be changed in the menu Configuration –> Channels –> SIP Channel Tab, under the SIP Option section.

Max length of incoming registration : 3600
Default length of incoming/outgoing registration : 120

There you go… The only thing left is to validate the configuration and make tests.
