[asterisk-ss7] Variable if call is national or not

[Dovid B]

Hi,

Here is my config:

signalling = ss7
ss7type = itu
networkindicator = national
linkset = 1
pointcode = 1607
adjpointcode = 9402
defaultdpc = 9402
cicbeginswith = 1
channel=1-15
cicbeginswith = 17
channel = 17-31
sigchan = 16
group=0

ss7_called_nai=national
ss7_calling_nai=national

I don’t remember why but I know that to work with our carrier I needed both
ss7_called_nai and ss7_calling_nai to be set to national. Now if I
understand correctly this is for calls TO my carrier? For calls FROM my
carrier I can set ss7_nationalprefix=N and then any caller ID or DID that
has N in front I know it is a national call?

Regards,

Dovid

If you set the
calling ss7_calling_nai=dynamic

in dahdi.conf then you can easily tell the NAI by prefix analysis

libss7 will prefix the number with ss7_subscriberprefix
ss7_nationalprefix or ss7_internationalprefix  depending on the nai
