I need an IVR with .NET

I need to write my own IVR or use an existing API.  I find this VoiceShot looks pretty good, but they cost quite a bit per minute.

But I guess the alternative is to host it myself, then I need a voice card and have a capacity bottleneck where I must limit the number of concurrent inbound calls, possibly to 1.

What kinds of solutions are there to create a .NET IVR solution to get found pieces of simple input?

What kinds of pricing alternatives are there?

Thanks,

If you need just one line and VOIP based then I suppose buying a softphone like Kapanga or using an open like OpenPhone (both of these have support for VXML), would be an easy solution. As for the voice card, I'm not sure what you mean by that, a T1/E1 card or a voice modem?
Have you looked into asterisk? Its the most used soft PBX out there and you can build simple IVRs with asterisk dialplans. I believe some TTS (text to speech) is also possible,
BTW, If you are looking for a speech based IVR, then you need an ASR (automated speech recognition) engine too and those are way too costly. There are some open source too like Sphinx but Im not sure how well they work.

I guess a voice card would be for a T1, which supports 24 concurrent calls, which I only need 1-3 calls at the same time.

I'll look into the software you suggested.

Thanks.

If you do not need speech rec then I think asterisk, YATE, freeswitch would be good options to look into.
