This page contains information on how to add and configure a Call Card Extension.
Overview
The Calling Card extension type allows the implementation of a calling card system on the VoipNow server.
For more information on how to define the account information, please visit Add an Extension section.
You can customize the Calling Card extension by setting up the options detailed in the section below.
If you do not want to finalize the process right away, you may skip this step and come back to it later on. Just click the Calling Card Setup icon available in the extension's management page.
Service behavior
Set up the way you need the Calling Card extension to behave.
Do not allow the user to call if credit is below <x> <currency>: Fill in the minimum credit a user should have when placing a call through the Calling Card extension; The currency that applies is usually the system's default currency.
Play when the call cannot be initialized due to lack of credit: Select the sound that should be played to the user running out of credit, upon automatically interrupting the conversation;
Play before disconnecting the call during conversation: Select the sound that should be played to the user that made the call, upon automatically interrupting the conversation.
User can interrogate the account credit: Applies if you want to give users the possibility to find out their credit value, before starting the conversation; As soon as the user is authenticated with one of the card codes, they are able to either interrogate their credit or make a phone call.
Service client must dial remote party number in <x> seconds: Specify the time interval (in seconds) within which the user can dial the remote party number. At the end of this time interval, VoipNow will consider the request as being completed.
The options described below allow you to customize the CallerID name that will be displayed on the callee's screen when the extension is calling public destinations.
Set by server: If it supports the CallerID function, the callee's phone terminal will display the extension owner's Contact name.
Set by equipment: If it supports the CallerID function, the callee's phone terminal will display the caller's name as set up from the phone terminal device.
Set by user: If it supports the CallerID function, the value defined here will be displayed by the callee's phone terminal; by default, the text box contains the extension's Contact name, but you can set the CallerID name to a custom alphanumeric value.
CallerID number in public calls
The options described below allow you to customize the CallerID number that will be displayed on the callee's screen when the extension is calling public destinations.
Set by server: If it supports the CallerID function, the callee's phone terminal will display the extension's public phone number.
Set by equipment: If it supports the CallerID function, the callee's phone terminal will display the phone number of that particular phone terminal device.
Set by user: If it supports the CallerID function, the value defined here will be displayed by the callee's phone terminal; by default, the text box contains the extension's phone number, but you to set the CallerID number to a custom numeric value with three or moral digits;
Currently using CallerID numbers
Allows you to choose one or several CallerID numbers that will be sent when an outgoing call is initiated.
The numbers available are the ones defined for the channel(s) (resource) used for routing the calls to public destinations.
The custom text box displays the CallerID number(s) currently in use; the default number is displayed using bold characters;
To add a CallerID number, click the Change link and a pop-up window will be displayed allowing you to manage the CallerIDs;
In order to be displayed in this list, the public phone number(s) defined for the channels (resources) used for routing the calls to public destinations must be assigned to the client owning this extension;
It is possible to assign CallerIDs associated with DIDs that are on the client pool, but that have not been assigned to any extension.
Please note that a CallerID can be set as default even if it has not been assigned to the extension's DID pool. To read more about it, go to the Calling Card Extension page in the VoipNow User Guide. To associate a CallerID with the extension, you need to select the corresponding checkbox and click the Assign CallerIDs link. To disassociate a CallerID, you need to select the corresponding checkbox and click the Remove selected link.
Do not send CallerID on public calls
Applies if you do not want your CallerID to be sent to public destinations. If the callee's phone terminal supports the CallerID function, it will display the Anonymous string.
Send public CallerID on internal calls
Applies if you want the public CallerID (when available) to be used for local and extended local calls as well. It allows the association between the CallerID of the Phone terminal user and an existing card code defined for the same CallerID.
Preserve original CallerID on transferred calls
Applies if you want VoipNow to keep the original CallerID when the call is forwarded between destinations.
Send SIP P-Asserted-Identity and P-Preferred-Identity headers
Allows the headers to be added to all outgoing INVITE requests sent from this extension.
The SIP P-Asserted-Identity header contains the caller ID number of the extension, e.g. P-Asserted-Identity:sip:0003*003@localhost.localdomain.
The P-Preferred-Identity header is sometimes used to indicate an additional identity of preference when there is a choice.
These headers are preserved only on outgoing external calls, e.g. P-Preferred-Identity: "John White" <sip:johnny@somedomain.org>.
