CT Messenger™ TAPI ActiveX Components

 TAPI compliant scriptable COM objects to quickly embed
 over-the-phone notification, text paging or SMS
 into your applications.

What is CT Messenger™?

CT Messenger™ 2.2 (Mint Components Inc.) is a component software solution designed to help developers to easily add over-the-phone notification, paging, and SMS functionality to their applications. CT Messenger Developer's Toolkit provides a set of scriptable COM objects (TAPI ActiveX) for sending voice messages to a Verizon, AT&T, or T-Mobile cell phone over any TAPI compliant hardware including a voice modem or telephony card. The same objects are used to send text messages to a pager or SMS-enabled cell phone. TAPI ActiveX objects from CT messenger can be used in Visual Basic (VB) or Visual C++ (VC).

All you have to do is create a call tree with message consisting of some text or the names of pre-recorded voice files (or both), one or more numbers to call, call time interval, etc., and submit it for processing to CT Messenger Server. The call will be scheduled and processed with a detailed report generated automatically. A report will bring information on the time and duration of the call, the type of answer detected, and the keys pressed by the recipient of the call.

TAPI Compliant COM (ActiveX) Objects

No more expensive and bulky hardware – CT Messenger 2.0 provides a set of scriptable COM objects that enable a Windows or Web application to bring important information to its users in the form of text pages, phone calls or SMS messages via any TAPI compliant hardware including a voice modem or telephony card. Unlike other programs of this type, CT Messenger uses software DSP algorithms for detecting the type of response (busy, no answer, voice answer). CT Messenger software does not rely on the answer detection capabilities of the underlying hardware, and it works with inexpensive voice modems.

CT Messenger standard features include:

  • Dialing-out over any TAPI compliant voice modem or telephony card
  • Providing built-in call and page scheduling and processing
  • Supporting software answer detection-identification (Busy, No Answer, Voice)
  • Providing built-in automatic text-to-speech conversion
  • Supporting unlimited call tree depth
  • Processing 'one-message-to-many-phone-numbers' requests
  • Merging pre-recorded voice files and text messages
  • Recognizing buttons pressed by the recipient of the call
  • Sending text messages to any pager or SMS-enabled cell phone using standard TAP or UCP protocol
  • Generating detailed reports on calls made/canceled/failed and pages sent
  • Using of several voice modems and/or telephony cards simultaneously
  • Storing and manipulating pre-recorded voice files
  • Using one calling and paging server by a number of intranet users concurrently

CT Messenger's Client and Server Parts

Designed for flexible deployment, CT Messenger software uses the client-server philosophy. The server part is called CT Messenger Server, and the client part – CT Messenger Developer's Toolkit. An application uses easy-to-handle CT Messenger Developer's Toolkit objects to create call or page requests (that contain call time limits, phone list, call tree, etc.), submit the requests for execution, and retrieve reports on requests executed, canceled, or failed.

In order to reduce the network traffic, CT Messenger software provides a mechanism for storing pre-recorded voice files on CT Messenger Server. CT Messenger Server is typically installed on a computer intended for scheduling and making calls and/or sending pages, as well as generating call and page related reports.

No tricky DCOM-like network configuration is necessary as communication between Client Side Application and CT Messenger Server is provided at the file level. Both CT Messenger Server and CT Messenger Developer's Toolkit can be installed on the same computer.
