Prepaid Distributed Calling Card via Packet Telephony
Feature History
This feature is also known as "Debit Card for Packet Telephony on Cisco Access Platforms."
The Debit Card feature gives service providers the ability to offer calling service with the use of debit accounting. This f eature was first introduced in Cisco IOS Release 12.0(4)XH. The following enhancements have been added to Cisco IOS Release 12.0(7)T:
•
Support for the Spanish language

Feature Overview
The Debit Card for Packet Telephony on Cisco Access Platforms is an application supported by the Cisco Interactive Voice Response (IVR) feature. The IVR voice scripts have been modified to use Tool Command Language (TCL) scripts.
Note
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/5300/cfios/cfselfea/0061ivr.htm
The feature components consist of IVR functionality in Cisco IOS software that work in conjunction with an integrated third-party billing system. The Debit Card feature includes the ability to maintain per-user credit balance information through the use of a billing system. When these features are implemented, the billing system and IOS software functions enable a carrier to authorize voice calls and debit individual user accounts in real time at the edges of a voice-over-IP network, without requiring external service nodes. This feature uses vendor specific attributes (VSAs) to communicate with the billing system.
A general, the Interactive Voice Response software infrastructure allows pre-recorded audio files to be combined dynamically to play the dollar amount of credit remaining, the time and date, and other information. The dynamic creation of the audio files (by combining prerecorded audio pieces) is limited to auidio files playing out dollar, time, and day information.
We recommend that you contact your Cisco marketing or sales representative to help determine which RADIUS server vendor best meets your needs. Also, refer to the marketing data sheet titled "Debit Card Application for Cisco Packet Telephony" that describes the Debit Card feature and provides a list of the specific features supported by RADIUS server vendors.
TCL Scripts
The Cisco Debit Card for Packet Telephony feature works in tandem with the Cisco Interactive Voice Response (IVR) feature modified with TCL scripts to provide voice prompts. These voice prompts are required to collect the necessary digits for accounting and settlement processes.
Before Cisco IOS Release 12.0(7)T and the introduction of IVR TCL scripts, IVR scripts were written in C programming language and compiled with the Cisco IOS software. This approaach tied the IVR application to the Cisco IOS software and also constrained releases of updated IVR scripts due to the Cisco IOS Release cycle.
Objects or commands written in C language that can be grouped together by the TCL script. When the script is activated by the incoming call, it activates the C codes in run-time mode and performs the work of these commands.
Note

TCL Script Summaries
The TCL IVR scripts that are supported by the Debit Card feature in Cisco IOS Release 12.0(7)T are described in summary as follows:
Two new TCL scripts have been developed for Cisco IOS Release 12.0(7)T:
•
•
Debit Card Features
Note
New feature functionality includes:
•
The call is authenticated using caller ID and PIN. The RADIUS server provides user credit (dollar) amount. The caller is then prompted to enter the destination number. The TCL script authorizes the call with the RADIUS server. The RADIUS server is expected to keep track of the caller's credit information, and it communicates with other billing servers, if necessary, to maintain or furnish user credit information.
An enhancement was added to Cisco IOS Release 12.0(7)T to allow two separate prompts for requesting the caller account number and password.
•
The RADIUS server is expected to maintain the credit information and furnish it to the script at the time of authentication. The TCL script plays a prompt that announces the remaining credit to the caller as dollars and cents. This is achieved by prerecording the words `one', `two', and so on, and then combining these recordings to form the final prompt. The format and resolution is $$$$$$.$$. The design is flexible enough to play any amount up to a maximum of 999999.99. For example, "You have one-thousand, three-hundred forty-five dollars and seventeen cents" is played.
•
The RADIUS server provides the credit (time) remaining to the script during authorization. The TCL script combines prerecorded audio files to form the final prompt and play the `time-remaining' to the caller. The time credit amount returned by the RADIUS server is expected to have taken into consideration the `rating' and time boundary overlaps. The prompt played to the caller is, for example, "You have five hours and thirty-five minutes." The design is flexible enough to play any amount of time up to a maximum time specified in the script.
If the time credit remaining is less than the configurable "time-out" value, the prompt played for example, "You only have two minutes remaining on your credit."
•
The RADIUS server maintains and furnishes time credit information during the authorization. The TCL script monitors the time remaining and, based on the configured value, plays a `time-has-run-out' message to the caller. The called party hears silence during this time. For example, if the timeout value is configured for three minutes, the prompt, "You only have three minutes remaining on your credit" is played.
•
This message is played to the calling party by the TCL script when the time credit has run out. The called party hears silence. The message is, for example, `Sorry, you have run out of credit.'
•
This feature makes it possible for the caller to make subsequent calls to different destinations without disconnecting from the call leg. Thus, the caller is required to enter the account ID number and PIN only once during initial authorization. To make subsequent calls, the caller needs to enter only the destination number. After talking with one destination, the caller is allowed to disconnect the call by pressing the pound (#) key on the keypad and holding it down for one to two seconds. If the # key is pressed down for more than one second it is treated as long pound (#). The called party is disconnected and an announcement is played to the caller, giving the new time, and prompting for a new destination number.
This feature also allows the caller to make additional calls if the called party hangs up.
•
Every time a caller enters a new destination number, the TCL script reauthorizes the call with the RADIUS server and obtains the remaining time and credit balance information. The TCL script then announces the amount of time remaining to the calling party.
•
The normal terminating character for the caller ID, PIN, and destination number is the # key. The caller may want to continue without waiting to hear the prompts. This TCL script will stop playing or will not start a prompt when it discovers that the caller wants to type ahead.
•
This TCL script stops playing announcements when the system determines that the caller has pressed any touch tone key.
•
–
•
The TCL script can be used to specify a number of digits in the user ID and PIN fields. This means that the caller can type all of the digits (without the terminating character) and the script determines how to extract different fields from the number strings. If the caller uses the terminating character (the pound key), the terminating character takes precedence and the fields are extracted accordingly.
•
The language is selected when the caller presses a predefined key. For example, `For English press one. For Mandarin press two.' The TCL script uses the selected language until the caller disconnects, the caller is asked only once, at the beginning of the session, for the language of choice.
Support for the Spanish language is introduced with Cisco IOS Release 12.0(7)T.
The ivr autoload Cisco IOS command is used during configuration to determine which set of audio files to load when the gateway server boots up.
•
The RADIUS server is expected to maintain information regarding off-net calls. During authorization, it provides this information to the TCL script. Based on the collected information, the TCL script has the ability to generate a prerecorded message or tone to the calling party.
•
Cisco vendor specific attributes (VSAs), which before this release were overloaded into the Session ID field of the AAA application.
•
A new field has been added to the Stop Record field. The data for this field is obtained from fields that maintain and tune voice quality. It is up to the user application on the RADIUS server to use this information and give credit to the caller if the call has unsatisfactory voice quality.
•
When voice prompts are not used for a period of time, they are swapped out of RAM. The swapping does not introduce undue delays in playing prompts. The most frequently used prompts remain in memory and are not swapped.
•
A general infrastructure is provided that allows combining prerecorded audio files to play the dollar amount , time, and day. An interface for the scripts to use this infrastructure is also part of this feature. Dynamic creation of the final audio (by combining prerecorded audio files) is limited to playing out dollar amount, time, and day information. For example, when the system receives a credit balance of $15.50, it combines the prerecorded audio files, "You have" "fifteen" "dollars" "and" "fifty" "cents" to make up this message.
•
If errors that are returned by the RADIUS server during authentication or authorization (use of the AAA application), the caller is allowed to retry the entry. The RADIUS server determines how many retries to allow. The caller is disconnected when the number of retries has exceeded the limit.
•
VSA Fields
VSAs are collected by the RADIUS server during the accounting process when AAA is configured with the Debit Card feature. (See "Configuring AAA" on page 22.) Data items are collected for each call leg created on the gateway. A call leg is the internal representation of a connection on the gateway. Each call made through the gateway consists of two call legs: incoming and outgoing. The call leg information emitted by the gateways can be correlated by the connection ID, which is the same for all call legs of a connection.
Use the H.323 VSA method of accounting when configuring the AAA application. (See the command "gw-accounting" on page 37.)
There are two modes:
•
Use the gw-accounting h323 syslog command to configure this mode.•
Use the gw-accounting h323 vsa command to configure this mode.Overloaded Session-ID Fields
The voice specific accounting information is coded into the 'session-id' field of the RADIUS record. Each field is encoded as an ASCII string. The fields are separated by a /. For additional information about the overloaded session ID refer Service Provider Features for Voice over IP. (See "Related Documents" on page 19.) Table 1 shows the VSA fields and a brief description of each.

Audio File Prompts
Cisco provides a set of professionally recorded English (U.S.) and Mandarin audio prompts to allow easier immediate integration and use of the Debit Card feature. The prompts are stored on the FTP server in the audio file format (.au.) To announce the credit available to the caller, the system concatenates a series of prompts to create the appropriate message.
The Cisco provided audio files are zipped and stored on CCO in the URL for the Software Support Center. The audio files need to be downloaded to either a TFTP server or into Flash memory. When the system runs, these files are copied into memory.
Note
http://www.cisco.com/cgi-bin/tablebuild.pl/tclware
Because there are a large number of prompts, and to ensure efficient use of system memory resources, all prompts are downloaded to a TFTP server. A basic set of audio files is downloaded to the system when it is initialized. The system removes less-frequently-used prompts from memory to conserve memory: when the prompt is needed, the system fetches the prompt from the TFTP server.
For languages that are syntactically similar to English, the audio file can be recorded and saved as the same filename to allow the system to construct the message properly. (See Audio File Naming Convention.) It is not mandatory to use the prompt set that Cisco provides. If the customer has access to a recording studio, prompts can be created or customized, as long as they are saved in the proper format.
Cisco Provided Audio Files
The following audio file prompts are provided by Cisco. A similar set is available in Mandarin. Not all of the audio file sets are used by Cisco IOS Release 12.0(7)T. Some are reserved for future use.
Support for the Spanish language is added to Cisco IOS Release 12.0(7)T. A similar set of professionally recorded audio files is available on CCO. The audio files provided are listed in Table 3 and Table 4.

"You can only make toll-free calls."
Audio File Naming Convention
If you record your own audio files, you must name them using the convention described in Table 4 for the TCL scripts to identify which audio file to use. The TCL scripts are designed to work with designated audio file names.
For example, when the Debit Card audio file for the caller to choose a language (en_lang_select.au) is played, ("Please press # 1 for English and # 2 for Mandarin"), if Mandarin is selected by the caller, then the TCL script calls the <ch> audio files to interact with the system.
Continuing with this example, when configuring the voice platform to process Mandarin audio files, use the call application voice command, with the language and set-location key words. When specifying the set-location parameter, the correct <language> <ch> specifier needs to be configured to interact with the TCL script. Therefore, when naming your audio files, make sure you include the language identifier for each file.
Note
Creating Audio Index Files
If you record your own audio files, you must also create an index file that contains a list of the audio files in URL format. An index file needs to be created for each audio file that needs to be downloaded from TFTP to memory. Use the ivr autoload command to download the audio files into Flash memory. See"Command Reference" on page 29 for additional command description and instructions for downloading using the index parameter.
When creating your audio file index, keep in mind that the filename and extension (au) are is actually the file's URL. Follow these recommendations:
•
•
•
•
•
Sample Index File
The following is a sample index file:
# tftp://jurai/tclware/au/en/auth_fail_final.au# tftp://jurai/tclware/au/en/auth_fail_retry.au# tftp://jurai/tclware/au/en/auth_fail_retry_number.au# tftp://jurai/tclware/au/en/auth_failed.au# tftp://jurai/tclware/au/en/ch_generic_final.au# tftp://jurai/tclware/au/en/ch_lang_sel1.auBenefits
•
•
Restrictions
The maximum call length is 18 hours. When a caller uses the Debit Card application, a call is disconnected after 18 hours, even if the caller has a dollar amount balance remaining. This limitation is due to the timing implementation in the software.

gw-accounting
To enable gateway specific accounting, use the gw-accounting command. There are three different methods of accounting. The H.323 method sends the CDR to the RADIUS server. The syslog method uses the system logging facility to record the CDRs. The VSA method collects VSA attributes. Use the no form of this command to disable gateway specific accounting.
gw-accounting h323 [vsa] | syslog
no gw-accounting h323 [vsa] | syslog
Syntax Description
h323
H.323 method uses RADIUS to output accounting CDRs.
vsa
(Optional) Vendor Specific Attributes are included in the RADIUS accounting. All the attributes that were included previously in the overloaded session ID are shown when this field is entered. See "VSA Attributes in Overloaded Session ID" in Table 1.
syslog
(Optional) Syslog uses the system logging facility to output CDRs.

12.1(5)XM2
The command was introduced for the Cisco AS5350 and CiscoAS5400.
Usage Guidelines
An index file is provided as a parameter to this command. This file contains a list of audio files (URL) to be down loaded from TFTP. These audio files (prompts) that are loaded using ivr autoload command are not dynamically swapped out of memory. They are considered as autoloaded prompts as opposed to 'dynamic' prompts. (see the ivr prompt memory command for details on dynamic prompts.)
Issuing the ivr autoload command initiates the process of down-loading files from TFTP to memory. The command only starts up a back-ground process. The back-ground process (loader) does the actual down-loading of the files.
The back-ground process first reads the index file from either Flash or TFTP. It parses the files line by line looking for the URL. It ignores lines which starts with # as comment lines. Once it has a correct URL, it tries to read that .au file into memory and creates a media object. If there are any errors during the reading of the file, it retries the configured number of times. If mode is set to 'verbose' the loader logs the transaction to console. Once parsing has reached the end of the index file, the back-ground process exits out of memory.
Perform the following checks before initiating the back-ground process. If one of the checks fail, it indicates the back-ground process is not started, and instead you will see an error response to the command.

12.1(5)XM2
The command was introduced for the Cisco AS5350 and CiscoAS5400.
Usage Guidelines
When both the number and size parameters are specified, the minimum memory out of the two will be used for memory calculations.
All the prompts which are not autoloaded or fixed are considered as dynamic. Dynamic prompts are loaded in to memory from TFTP or Flash, as and when they are needed. When they are actively used for playing prompts they are considered to be in 'active' state. However, once the prompt playing is complete, these prompts are no more active and are considered to be in 'free' state.
The free prompts either stay in memory or removed out of memory depending on the availability of space in memory for these free prompts. The prompt-mem command essentially specifies a maximum memory to be used for these free prompts.
The free prompts are saved in the memory and are queued in a waitQ. When the waitQ is full (either because the totally memory occupied by the free prompts exceeds the max. configured value or the number of files in the waitQ exceeds max. configured), oldest free prompts are removed out of memory.
