Telephony programming -
ExceleTel and TeleTools make it easy!
|
I know, you've heard it before, and now we've said it again. So
why don't we prove it? OK, we will. The simple example below
shows just how easy it can be.
This example explains how to create a simple CallerID program with
Visual Basic and ExceleTel TeleTools. The program displays both CallerID name and number on
an incoming call.
|
A few clicks and 4 lines of code
So what does it take to get this done with TeleTools? Exactly one
TeleTools component and 4 (that's right four) lines of code.
Here's the process:
1. Start Visual Basic.
2. Create a new application.
3. Add the ExceleTel TeleTools components to the
Visual Basic tool bar.
4. Drop two labels and the TeleTools etLine
control on the form.
5. In the form load event handler routine select and
activate the device.
6. In the etLine OnCallerID event handler routine set
the label captions to display the CallerID information
7. Run the application.
8. Make a telephone call to the device.
Yes, that is it. It's that easy!
Comparison -- With ExceleTel / Without ExceleTel
OK. So how does this compare to doing the same thing
without ExceleTel and TeleTools? The table below shows a quick
comparison that's probably already obvious to you.

turn for all kinds of help with telephony and TAPI? |
The
ExceleTel team and it's years of telephony experience |
The
volumes of documentation in your $2,800 MSDN subscription?
Expensive consultants? Outdated books? Inconsistent or
irrelevant answers from on-line newsgroups? Good luck. |
| Who tests the
guts of the TAPI code? |
ExceleTel
- you get well tested components in use by a multitude of
developers world-wide. |

Yes, this is a very simple example. What
about more complex applications like the ones you are likely to
develop? Maybe you'll be playing or recording wave files, depending
on DTMF responses, doing transfers, creating conference calls, call
centers, voice response systems, 100 line applications, whatever...
NEED MORE PROOF?
Here's a program that shows you exactly how to get
started with a real-world application, a program that allows you to
select and activate your TAPI telephony devices, input numbers and
dial calls. It tracks call progress and even shows incoming
calls and caller id. In addition, one button click launches
our TeleScope that not only shows you more diagnostic and logging
information, but opens up virtually unlimited world of
functionality. Just hover over any button, field or menu and
see the method, event, or property that you need to use in your
program! Click HERE

Every additional
piece of functionality that you need means more learning, more hurdles,
more time. But not with TeleTools! TAPI can be
very complex, and the API for a particular piece of hardware not much
better and you lose the ability to work on multiple hardware
platforms. TeleTools gives you the best of both worlds. The investment in your time and money
by trying other options can take the fun and the profit out
of the project. Let us do the hard work for you!
It's really no comparison, so do not go it alone. ExceleTel
and TeleTools saves you time,
money, and aggravation. Try
it, or buy
it today.
