Dave,
my last note refers to UA -> asterisk B -> Mobile -> Nokia e60 or LG 310
-> PSTN
since I've already have it configured the test are done locally
with nokia the audio is a bit better compared to LG, but with some static
noises on the PSTN side, with lg the voice is not "smooth" has "holes" or
"interrupts" on both sides
I know little about BT, but a wild guess, could it be SCO MTU? dunno also
if I can change it...
Also, is there some recoding taking place? as far as I see from googling
around, SCO is running on ulaw, right?
