your asterisk box has to do audio conversion, its getting bogged down
Thanks for your reply, Jason. Two further questions:
1) I thought all networking would be done in the card, not taxing CPU much?
2) I get reasonable quality (and no significant network blockage) when I
answer call from Console. In this case, Asterisk also needs to "transcode"
audio into the sound card, right? G.711 is supposed to be the least taxing
CODEC, and I'm pretty sure I'm using G.711 between VoIP extensions (hence no
transcoding between VoIP and FXO. (disallow => all, allow = ulaw)

I'm greatly surprised when testing an Asterisk box with 802.11g. Here's
the topology:
VoIP caller --- 802.11g --- Asterisk --- 802.11g --- VoIP extension

FXO ___ PSTN extension
When I call a VoIP extension on that box (from a VoIP extension), voice is
good. But when this box tries to bridge the call with a PSTN extension,
voice is completely broken. And it's not because of the cheap X100P -
when I ping the box, round trip is >4,000 ms, most of the time causing
timeout. Once the call hangs up, ping time dropped to 1-2 ms. Ping time
started to surge even when FXO is simply ringing.
If VoIP to VoIP extension call uses re-invite (which it did), voice is
also good in the Console channel.
How can voice traffic stall 802.11g? (I haven't checked, but CODEC is
likely ulaw.)
