问题
Is it possible using a Windows Server, .NET, C# or PHP to send a SMS text message to q customer's cell phone without depending upon a third-party service (excluding an API provided by a phone company).
My require is to use SMS text messaging to automate authentication when resetting a customer's password, and I have security issues were I'd rather not use a third-party. The more I can keep this internal to our project the better (unless you can justify security in your answer).
UPDATE:
We've decided to use a SMS relay app and this was so easy to implement. There are many apps that already do this. Here is one I'm going to try.

you can build a simple mobile app that can query your api and send messages directly from the phone its running on. simple, cheap and you're in control!
we have this solution in a project Im working on atm and it seems to work great. Look up http request and using sms/send message. At least on Android this can be done with just a handful of lines of code :)

You could always use a library like SMSLib: http://smslib.org/
You will need to purchase a device that SMSLib can work with

To the answers posted by others I would add the following:
use Gammu (or Wammu): attach a phone or gsm modem with usb to your computer and send sms messages using Gammu. Pros: cheap solution, proven by users. Cons: work need to be done with installation and setup of Gammu/Wammu
use a device called: hardware sms gateway (see google search results for possible examples). Pros: reliability and security (those devices has usually built-in database, fail-over mechanisms, etc.). Cons: this costs money, so you've got to make investment.
