VOIP Server Hardware Requirements

[asifsolkar]

Hi Guys,

I am developing a VOIP Application using java. The development has gone quite well. The problem i am facing is When i deploy it on server it doesn't work.

Voice chat works well on my desktop both server and client. But On Server it doesn't work . What configuration do i need on server so that it can work. Is there a specific sound card to be installed.

I have a remote desktop access to the server. To run the server app i double click on it and it starts working but connection for sound socket fails

Here is the error i get :

Exception caught while passing socket to ivConnectionjavax.sound.sampled.LineUnavailableExc eption: line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

Seems to me memory is not enough for rendering voice. I found quite same thing on a different application few years back, little-endian always described about lower memory.

What does that mean ?

Does it mean usb 2.0 sound card cannot be used by java , does it need onboard sound card ?

[Eranga]

No way pal. I thought you may used USB 1.0. It's not support in most of the cases of VOIP applications.

Again I told you this is because of the lower memory. Because of that system can't make the connection, and you got the line unavailable exception there.

There should be one reason too. May your connection(communication line) used some other application.

What happened to your MIDI drivers? Update and try. It may fix the issue, because it's the protocol define the digital communication.
