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
