Hi,

I am one of those probably few Asterisk users who decided to give it a try as a soft phone. I have installed it on my ARM/OMAP based Amstrad E3 (Delta) videophone and get quite good results. For now I use 1.4.26, since I was not yet able to build 1.6 with OpenEmbedded.

My sound driver is ALSA, so I started with chan_alsa. It's behaviour was not very bad, but there were random problems with incorrect signalling, not acceptable for a common user.

After switching to chan_oss, I found that during some operations it was consuming all processor power. So it appeared not to be an option either.

I got back to chan_alsa, investigated the problem and found a solution that works for me. In fact, I have followed corresponding bits from chan_oss to get it working.

Created and tested against asterisk-1.4.26.
