I don't know about X-Lite, but sjphone seems only to support OSS. One
of my requirements is ALSA support. Thus linphone and gnomemeeting.
But, interestingly, gnomemeeting seems to be the only client capable
of full duplex audio using ALSA+DMIX+DSNOOP+ASYM.

Yeah. It supports STUN too, which seems to be the silver bullet for
SIP. So I'm thinking the problem is more asterisk related. That's why
I asked about gnugk. It seems to have more NAT translation support
than asterisk, but my attempts at a working config haven't worked so
far.
