I have the task of integrating the following functionality into our VC++6 application: The ability to send both voice and text messages to an IP phone or group of IP phones. By Voice messages I mean placing a call.
Can someone please direct me to which API(s)/SDK(s) I should use?
I have looked through the CCM_API_Overview_3_3_3.pdf; there are quite a few technologies available. Any assistance in helping me narrow down what I should focus on is much appreciated.
