chan_ss7 uses the dial plan to decide if an incoming call number is complete,
or if it has to wait for further address messages (SAM) before accepting the
call.
In your setup, chan_ss7 tries to match the incoming call number (dni) against
the dial plan in context "ss7" (you have specified context=ss7 in ss7.conf).
But the dial plan context "ss7" is empty in your extensions.conf. I suggest
you put the dial plan logic in that context, or change the ss7.conf to have
context = default.
Best regards,
