Call Completion / SC.SmartConnect

Voicemail + MCA + CallBack an Undefined + Voice Call Auto CallBack + Pay4Me + Notify Call

Sometimes subscribers can not establish connection with each other, for example, if a subscriber is busy or not available, misses a call or does not have sufficient funds to make a call.

The SC.SmartConnectTM platform provides the following services to ensure the connection of subscribers in mentioned situations:

  • Voice mail
  • Notifications about a subscriber appearing in the network and about missed calls
  • Various options of call back
  • Calls at the expense of the call recipient
  • Promised payment and more

When performing the voicemail functions, SC.CallCompletion will independently record voice messages, store them, notify the recipient of an incoming message, and provide an IVR interface for playback.

The system has a modular architecture and is easily scalable according to the customer’s requests.

  • Notify Call. This service is made as an alternative way of notifying subscribers signed up for the MCA and the Promised Payment services. If notification of called party B is required the Beep Call service can generate a fake call in the way as it was originated from the number of party A. In this case connection is not established, but the called party will see a real a missed call on his/her mobile phone’s screen. Unlike SMS notifications this service provokes more call backs
  • The CallBack an Undefined service allows subscribers to order a call back to hidden numbers. Subscriber requests can be received in various formats, such as SMS, USSD, IVR. A subscriber (service requester) can hide the phone number realizing a call back or leave it visible.
  • The Voice Call Auto CallBack service allows to order an automatic call back if a call recipient is busy or out of network. During a call to such subscriber’s number a proposition to order the service is played. After the request is accepted the platform starts tracking the status of the subscriber who was tried to connect with. As soon as the subscriber is available (not busy), the platform initializes the request processing and makes a call back. The procedure of dialing and switching to a subscriber is flexibly configurable. The platform also can send the proposition to benefit from the USSD Push service. The service requester is informed about the request status by SMS.

      2. Static voicemail (full configuration capabilities and extended message storage period)

Benefits & advantages

SC.CallCompletion has the following advantages:

  • Documented HTTP interface to manage the voice engine allowing the MNO to establish new voice services based on the solution

The solution is characterized by high reliability:

  • All system components are redundant
  • The performance reserve of the system is at least 50% of the planned load
  • The system includes backup tools. Both full and incremental backup are possible
  • Backup copying does not interrupt the system’s operation

Integration scheme

In the minimum configuration, the system is installed on 2 dedicated servers. The servers are connected to a fail-safe cluster. SMSC integration is optional.
