Can you send updated gateway config? IS region-aqsho assigned to gateway and ATA?

I said you should remove "fax protocol pass-through g711ulaw" from all your dial-peers
configure
voice service voip
no fax protocol pass-through g711ulaw
fax protocol none
I still see this in your configs...
Please remove and try again
