Google Talk (XMPP/Jingle/jabber) client needed


we need a skilled developer for creating a messenger application for us.

The project has 2 parts.

Part I:


Your messenger should allow:

-Text messaging

-Voice Chat

-File Transfer

-Registering a new user

-adding/deleting a friend to the friend list amnd showing their online status

(very simplistic GUI like Google talk; see screendesign PNG that we have attached to this message)

It should be compliant to Google Talk allowing users to chat and to voice-chat / VoIP with Google talk users. Google Talk is a jabber client with extensions for voice chat. Google has opened their protocols and created some libraries that you can probably use (see [url removed, login to view] ).

***It's important that your client supports voice chat with other google talk users!***

Once your client is working, you need to deliver it as part 1 of the project and we will do some testing. When it's fully working we will enter part 2 of the project.

Part II:


Once a voice call arrives, your program will record it as long as the person speaks. When thre is silence in the line, your program will save the recording to a wave file and invoke a method from a DLL of us. We will convert the recording and return it to you. You then need to play this recording to the user and continue.

For example, imaging two people having a chat (current user=Tina):

Tina: "Hi Tom, how are you"

Tom: "I'm fine, thanks." (pause for 2 seconds)

Tom: "How are you?"

Tina: "I'm fine as well."

The process with your application will be the following:

Tina: "Hi Tom, how are you"

-> Your app will record this into a wave file and pass it to us.

We will convert it and return a new wave which you will send it to Toms client

Tom: "I'm fine, thanks." (pause for 2 seconds)

-> Your app will notice the break in the chat and record the sentence

into a wave file and pass it to us.

We will convert it and return a new wave which you will play on the speaker

Tom: "How are you?"

-> same as above

Tina: "I'm fine as well."

-> same as above

Basically, we will intersect with all sound and we will perform a conversation before a sound is played or sent. While we convert the sound file, yur application should show a "please wait" on the screen.

There has to be the same with text messages:

Again, we will convert all text and return it to you before it is dieplayed or sent.

The user should have a checkbox in his chat window called "convert all". If it's checked, you will pass us all messages/voice for conversion. Otherwise you can handle them without invoking our method.

Some general requirements:

-You will have to provide clean code and seperate the GUI for the logic components via different assemblies/classes. We need you to create a short example application (windows forms or wpf) to demonstrate all features (see attached screendesign).

-You can use C# or C++ internally but all main functions that you create need to be wrapped/available via C#. Your example GUI should be in C# as well.

-Your solution needs to work on Windows XP, vista and windows 7 with 32 and 64 bit.

-In case of any problems, we expect bugfixing and support for your code for at least 4 weeks after project completion.
