This is called "automated attendant". Most, if not all, voice mail systems have a built in auto attendant function. Some systems also have an auto attendant available seperate from a voice mail.
I am not certain as to why you are trying to do this via a PC...
The possibility of doing this yourself and the method for doing it, is going to vary considerably from system to system.

thanx for the reply.

the thing is i dont have access to the pbx it self, and if i did, i am not sure know how to do it.

The reason i am using a pc is because this is the first step, after completing this step, i am gonna move to some bigger telephony application, i.e. lets jjust say this is a proof of concept of what is to come.

also i am wondering if a modem wont work, i am going to invest in a dialogic card, but i am not sure which one will work with a digital PBX, or lets say both digital and analog..

do u have any idea on which card i should get???

thanx a lot.

It’s all in the ‘dial’ strings and each pbx is a little different ‘proprietary’. Basically you have to get your application to emulate a telephone set connected to the pbx. Thus, most applications referred to as “Third Party Applications”, communicate to and with the pbx via Analog ports or Digital Ports.

As an example:

Scenario: You have a VB script that associates ‘button clicks’ with actionable items. Say, button 101 = ‘Conference Call”. The pass-thru “Data Access Object” portion of your code would;

1. Call “Obtain dialtone” code, [Gets dialtone from the switch]
2. If button 101 = “0” Then ..Send a spre code and Conference Call code,
3. The switch will handle the call connection for you,
4. Wait or For timeout action, or error code check and implementation,
5. If Not “Idle” Then back to 4,
6. IF Idle Then send “Disconnect” code.

(Of course the common comm to a switch from a third party application is via a series of ACK (acknowledge) commands.)

That’s basically it…

Some other things to consider;
1. Digital ports are expensive resources, so If you can implement your program via analog ports that would be best,
2. Queues are a great way to allow the ‘Switch’ to stack calls for you,
