[asterisk-ss7] SS7 Called Nature of Address Indicator - problem

The configuration items you're using (ss7_.*prefix) relate to libss7, not chan_ss7.

You could swap over to libss7.

Alternatively, if you're using chan_ss7, you need to modify the source, as it currently doesn't identify subscriber calls.

All the relevent code is in l4isup.c (at least for chan_ss7 version 1.3) in the following functions:
isup_phonenum_check
isup_called_party_num_encode
isup_called_party_num_encode_no_st
isup_calling_party_num_encode

It's relatively trivial to modify as the code is quite straight-forward.

  In international calls (start with 00) it´s ok
  In national call (starts with 0) it´s ok
  but in subscriber call (don´t start wih 0) automatically set like 'national'

  I´m using  Zaptel Version: 1.4.10.1
  chan_ss7 1.2.1
  asterisk 1.4.20.2

  I found  ss7_internationalprefix = 00
  ss7_nationalprefix = 0
  ss7_subscriberprefix=0S
  but zaptel doesn´t accept this configuration.
