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. --Greg ----- Original Message ----- From: equis software To: asterisk-ss7 at lists.digium.com Sent: Monday, February 08, 2010 5:06 PM Subject: [asterisk-ss7] SS7 Called Nature of Address Indicator - problem 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. ------------------------------------------------------------------------------ -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-ss7 mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-ss7 -------------- next part -------------- An HTML attachment was scrubbed...
