Default Sound/call quality tweaks (on an SPA3102)...

Hi All,

I've just started using my SPA3102, and wasn't impressed with both the
sound quality of an incoming PSTN call - I don't know if the person on
the other side was using a poor cordless phone (?) - and an outgoing
call to a mobile in a diferent country - not the easiest scnearios, I
know...

Still, I've changed "Jitter buffer adjustment" from "up and down" to
"up only" - trying to increase the buffer so the sound doesn't have
cuts in the middle, like I noticed today :-(
Does this seem like a reasonable option?

Besides, I'm considering fidling with codecs... Apparently G726 should
allow for fair quality, with smaller packets of data. Right, or not so
much?? I'm trying G726-32

Any other codec sugestions, and why you'd choose them? (I'm presently
using G711a)

Oh, since the SPA3102 is attached to a router port, I've already setup
in the router high priority to that port over the others - wich have
normal priority.

Regards,
Jose
