Fair enough (I've never used Voice Alert, and I'm not familiar with  
the Alinco unit.) I thought that maybe the TNC wasn't hearing any  
audio because of the tone squelch.

As for getting into a gateway, I see from aprs.fi that your POO-1 digi  
is getting in ok, so maybe it's a hardware issue. Listen to the audio  
on another rig to see if there's any obvious distortion. A complete  
lack of audio would do it too! :-)

Your settings look broadly ok to me, but as an experiment you might  
try changing the "gpslj" to "aprs", just in case some digi on the way  
is balking at the "GPSxxx" bit. I wouldn't expect this to be the case,  
but it's worth a try.
