ss7_called_nai=dynamic parsing bug or config mistake?

Hi,

Calls to national NAI numbers are working OK, but when I try to call a 
number with a subscriber NAI,
subscriberprefix gets replaced with nationalprefix...

chan_dahdi.conf excerpt:

ss7type=itu
ss7_called_nai=dynamic
ss7_calling_nai=national
ss7_internationalprefix=00
ss7_nationalprefix=0
ss7_networkroutedprefix=N
ss7_unknownprefix=U
ss7_subscriberprefix=S

extensions.ael excerpt:
_1XX            =>      { Dial(DAHDI/g2/S${EXTEN},60); Hangup; }

CLI debug:
     -- Executing [110 at Network:6] Dial("SIP/sip-00000001", 
"DAHDI/g2/S110,60") in new stack
     -- Called g2/S110

Notice that S110 gets replaced with 0110:

                 Called Party Number:
                         Nature of address: 1

                         [ 05 81 10 10 01 0f ]

I've also tried replacing ss7_calling_nai=national with dynamic, but

Am I doing something wrong not noticing something obvious or is it a bug 
in the dynamic nai parsing function?

Thanks in advance for your time,
Kind regards,
Vahan
