How does Prepaid Calling Card Operation work?

As a PPCC service provider, operating a VoIP Gateway/Switch, you would arrange to have printed for sale Prepaid Calling Cards of certain designs and of certain face value (please refer to the section on printing of PPCC cards below).

The card has printed on it 2 pieces of essential information: (a) the telephone number the customer is to dial to reach the VoIP gateway/switch and (b) a card number , also known as PIN (Personal Identification Number) that is a unique number that is required by the PPCC service platform for authentication (or validation) as to whether or not the caller (customer) should be permitted to use the service in the first place.

Upon positive authentication, the PPCC service platform then voice-prompts the caller to enter the Destination Number (DN) of the telephone number that he/she wants to reach.

The PPCC service platform calculates the maximum length of time the caller has for the call based on the amount of credit in his/her account and the per minute rate applicable to the DN and then informs the caller of it.

Generally the call flow is as follows:

  1. Gateway/switch (GS) answers the call from the user
  2. GS plays the greeting prompt
  3. GS plays "Please enter your account number"
  4. GS collects the digits of the account number dialed by the user
  5. GS sends the account number to Ecocarrier Service Platform (ESP)
  6. ESP verifies the account number from the GS
  7. ESP sends the verification result and account balance to GS
  8. GS plays "Your account balance is ..."
  9. GS plays "Please enter the destination number followed by pound"
  10. GS collects the digits of the destination number dialed by the user
  11. GS sends the destination number to ESP
  12. ESP verifies the destination number and calculates the maximum call duration
  13. ESP sends the maximum call duration to GS
  14. GS plays "The maximum duration for this call is..."
  15. GS routes the call
  16. GS plays "You have one minute remaining in this call" when (if) the elapsed duration of the call is one minute less than the maximum
  17. GS waits for the end of the call
  18. GS sends the CDR (Call Details Record) to ESP
  19. ESP saves the CDR from GS

Service Platform Requirement

The service platform consists of QiiQ Communications Inc.'s Q-Regime, Q-Bill-R and Q-PPCC Server. One may acquire the integrated system from QiiQ and operate it as an ITSP (Internet Telephony Service Provider) to provide VoIP-based services to clients. This would imply that one has to also maintain the service platform and establish and maintain relationships with carriers for call termination services – an undertaking that requires a great deal of knowledge of network management and of the VoIP industry.

A better approach is to take advantage of the established service platform of Ecocarrier Inc. for all the OSS (operation support system) functions and simply use Ecocarrier's service platform and call termination services.

Internet Access Infrastructure Requirement

in the case of owners/operators with VoIP Gateways or IP Phones

Ideally the owners/operators should have access to Internet via Broadband Network such as ADSL or Cable Network or T1/E1/PRI or satellite service for access to Internet service provider.

For small capacity operation in countries where broadband service is difficult to come by, the PPCC service provider or his clients can make use of single-port VoIP gateway with built-in 56K modem or an IP Phone with built-in 56K modem for dialing up to the local ISP for Internet access.

Where such facility is not available, Internet access can be obtained by infrastructure build-out based on

(a) Fixed Wireless installation such as 2.4 GHz, 5.8 GHz solution in the license-free ISM Band or 3.5 GHz solution the licensed 3.5 GHz Band or

(b) Satellite Ground Equipment support by Satellite and Teleport services for satellite transport and Internet access or

(c) a combination of (a) and (b) with system integration based on QiiQ's server.

Please refer to the network diagram below that depicts the various kinds of endpoint devices that can be used for accessing the Q-MXU service for making VoIP calls either in a postpaid operation or prepaid operation.

VoIP gateways, IP Phones or Softphone to suit every user situation:

(a) For large capacity PPCC operation use large VoIP gateways/switches such as

Tenor CMS 480, CMS 960 Tenor DX2024, DX2030, DX4048, DX4060, DX6120, and DX8120 Optional GSM gateway: GoldenGate Multi-Cell PRI-GSM Gateway Cisco Universal Gateways AS5350, AS5400 and AS5850
and a GateKeeper

(b) For medium capacity PPCC operation use VoIP gateways/switches such as

Tenor DX2024, DX2030 Tenor Analog AXT1600/2400, AXG1600/2400, AXE1600/2400, AXM1600/2400
Optional GSM gateway: GoldenGate Multi-Cell PRI-GSM Gateway

(c) For small capacity PPCC operation use VoIP gateways/switches such as

Tenor Analog ASG200/400, ASM200/400 Tenor Analog AXT800, AXG800, AXE800, AXM800 VoIP!Edge Q-4FXS VoIP!Edge Q-2FXS-2FXO Airello Q-WiFi-Fone VoIP!Phone Q-FONE-XUV

(d) For small capacity installation with only dial-up access to the Internet Service Provider use

VoIP!Edge Q-1FXS+56K

Equipping the VoIP Gateway/Switch with GSM Gateways

In many countries, the per minute rate for calling from one GSM handset to another GSM handset is significantly lower than the per minute rate for calling from one GSM handset to a fixed line telephone. In such cases, it is advisable to include an analog GSM gateway for use with an analog VoIP gateway/switch and a digital GSM gateway for use with a digital VoIP gateway/switch as depicted in the network diagram below.

Each channel of the GSM gateways has to be equipped with one or more SIM cards supplied by a local GSM operator so as to be able to receive an incoming call originating from the service subscriber/caller and to forward the call to the VoIP gateway/switch to go through the prepaid calling card operation as described above.

The single-channel analog GSM gateway, GoldenGate GSM-SMS FCT, can be equipped with one SIM card; whereas the GoldenGate Multi-Cell PRI-GSM Gateway digital GSM gateway can be equipped with up to 4 SIM cards per channel.

The multiple SIM cards feature is important in markets where there are up to 4 GSM operators providing GSM services. A common practice of a GSM operator is to offer special rate concession to its subscribers for calling Mobile Numbers that are within the same network of the GSM operator in various forms such as (a) one flat rate for calling any Mobile Number within the GSM network or (b) special discounted rates for calling Mobile Numbers that are within the GSM network.

As an ITSP, you would want to be able to select the appropriate SIM card in the GoldenGate Multi-Cell PRI-GSM Gateway to use to call a certain Mobile Number that is the Destination Number for call termination of an incoming IP call so as to take advantage of the concessionary rates. This can amount to very substantial savings.

  • specification of the format of PINs to be printed on the cards to suit the automated printing process
  • the face value of each card which may be in $ amount or Unit.
