TAPIEx replacement

I am looking for a component that can allow me to interface the Microsoft Speech Engine (TTS) through a SIP Phone. We currently us an Active X Component called TAPIEx with a Speaker Phone Modem on our Call Out PC’s, but we are moving to SIP/VOIP soft phones. Can you help? What we need to do:

Programmatically dial a number
Play a custom TTS message
Record a DTMF Key Press response

Our development environment is VB.Net We use a handful of Desktop PC’s to make our Call Outs. Thank you for your time and I hope to hear from you soon

All Voicent products support VOIP (SIP or Skype) as well as modem, and TTS engines are supported by Voicent TTS Plug-In, so you have come to the right place. All Voicent products also have command line and web (HTTP) interface, so you should be able to drive Voicent dialer programmatically. We suggest you download the software and try Voicent BroadcastByPhone autodialer first. If you want to do predictive dialing or power dialing, then try Voicent Agent Dialer.

You can also directly interface with Voicent Gateway and IVR Studio. For more information about program integration, please see developer section of our website.
