VOIP for stored audio files

[faizan]

Hi all,

Can you suggest any open-source software which supports VOIP on
omap3530 an Angstrom or ubuntu OS,
I have tried with Ekiga, but it gives segmentation error when i open
it, more over it doesnt support transfer of stored audio via VOIP. I
have even tried with aMSN, but it supports transfer of files via FTP.

I need some software which will support stored audio transfer via
VOIP.

Kindly oblige.
