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

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
