Assuming that you are actually dialling the numbers correctly with your
extensions.conf / Dial commands, then you might need to experiment with:

; PRI Dialplan:  Only RARELY used for PRI.
;
; unknown:        Unknown
; private:        Private ISDN
; local:          Local ISDN
; national:       National ISDN
; international:  International ISDN

pridialplan=national

in /etc/asterisk/zapata.conf - this is most likely what is going wrong.
