Introduction
The Telephony API implementation in Windows CE is a subset of the Microsoft Telephony Application Programming Interface (TAPI) version 2.0 and some parts of TAPI version 2.1. TAPI provides an application programming interface (API) that simplifies and abstracts the details of making telephony connections between two or more devices. TAPI abstracts call-control functionality to allow different, and seemingly incompatible, communication protocols to expose a common interface to applications through its support of telephony service providers (TSPs).

About DynTapi Library
The Teksoft DynTapi Library comes as a wrapper to the existing TAPI interface, with the demonstrated purpose of providing a simpler interface for the most important telephony functions.
This Library can be used with various development tools and can be called from projects written in several well known languages like C++, C#, Visual Basic, etc.

Using DynTAPI you will be able to:
- write robust telephony applications without loosing time reading about all 100+ TAPI native functions
- detect the CALLERID with less then 10 lines of code
- dial numbers, or place current calls on hold
- retrieve the network operator name or the network signal in an easy way
- dial data connections, receive and send binary data over the phone connection
- create simple VoIP / Phone / Encrypted Phone applications
- toggle the Speakerphone on and off
- control the hardware, toggle the Radio on and off
- register/unregister from the mobile network
- handle DMTF tones
- handle all the network/API errors
And many more.
