Question
hi,
We are developing software namely "CallCenter Management".

(1)how can I come to know when the recerver is picked up and when the receiver is put down?

here the matter is of VOIP. when receiver is attached to modem then there is no problem. we can use TAPI control. But here matter is somewhat different.

(2) the moment receiver is picked up conversation starts which will last until receiver is put down.
ok.
now the moment conversation starts we receive data in bytestream.
these group of bytestream includes not only VOICE data but also some other data. for example, if we are interacting with database then that intearaction will also be converted to bytestram.

so finally problem is how to identify VOICE data among the cluster of bytesream. Similarly after finding VOICE data we need to convert that portion of VOICE data of bytestream into ".WAV" format and store that ".WAV" file into database. and also whenever we need to hear that VOICE data we should be able to playback that .WAV file in our application.

summory of project:-
This project is to put watch on every telephone call handled.
Next day when the HEAD of department comes and hear the voice data he can measure the performance of his employees.

We use ASP.NET 1.1, C#.Net 1.1,
Database server is SQL server 2000.
OS Windows 2000.

Please send me the code for doing this. Because developing this things requires more time and I don't have time as deadline for this project is coming nearer day by day.  

Answer
Hi

Sounds Interesting! Sorry I never worked on VOIP.  Are you doing for a project(academic) or work related project?

You need some third party SDK to support this.  Sometime back I got a newsletter something related to VOIP.  This site may help you.
