No more expensive and bulky hardware OCo 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.
