Hi,<BR>
<BR>
There is a Open source IP Phone called Twinkle. You can find it at <A HREF="http://www.twinklephone.com/.">http://www.twinklephone.com/.</A><BR>
Im not sure if they convert the ULAW and other formats to linear PCM but its worth a look. <BR>
<BR>
Good Luck with your Soft phone<BR>
<BR>
Regards<BR>
