hello,
we have an sangoma AFT104 card installed on asterisk box connected to
alcatel switch via ss7.
we use asterisk box for db lookup; call enters asterisk box then
an agi script performs some db lookups then returns call to alcatel
with a single command like this:
EXEC Dial DAHDI/g1/81B01XXXXXXXXXX
the problem is chan_dahdi & libss7 cannot send alphanumeric extension
to alcatel.
in alcatel "B01" seen as "001".
is there any way to send alphanumeric extension over ss7 with
chan_dahdi & libss7.
thanks
huseyin
