Sorry, I'm confused you refer to two places, but they seem to be identical? Are you sure there's no mistake? I have this in mu isup.c: static char char2digit(char localchar) { switch (localchar) { case '0': return 0; case '1': return 1; case '2': return 2; case '3': return 3; case '4': return 4; case '5': return 5; case '6': return 6; case '7': return 7; case '8': return 8; case '9': return 9; case '#': return 0xf; default: return 0; } } static char digit2char(unsigned char digit) { switch (digit & 0xf) { case 0: return '0'; case 1: return '1'; case 2: return '2'; case 3: return '3'; case 4: return '4'; case 5: return '5'; case 6: return '6'; case 7: return '7'; case 8: return '8'; case 9: return '9'; case 15: return '#'; default: return 0; } } Regards Rennes Neps -----Original Message----- From: asterisk-ss7-bounces@xxxxxxxxxxxxxxxx on behalf of Joeri van Dooren Sent: Mon 10/12/2009 17:19 To: asterisk-ss7 at lists.digium.com Subject: Re: libss7 problem with dialing a non numeric string within libss7 in isup.c static char digit2char(unsigned char digit) { switch (digit & 0xf) { case 0: return '0'; case 1: return '1'; case 2: return '2'; case 3: return '3'; case 4: return '4'; case 5: return '5'; case 6: return '6'; case 7: return '7'; case 8: return '8'; case 9: return '9'; case 12: return 'c'; case 13: return 'd'; case 14: return 'e'; case 15: return '#'; default: return 0; } } and for: static char digit2char(unsigned char digit) { switch (digit & 0xf) { case 0: return '0'; case 1: return '1'; case 2: return '2'; case 3: return '3'; case 4: return '4'; case 5: return '5'; case 6: return '6'; case 7: return '7'; case 8: return '8'; case 9: return '9'; case 12: return 'c'; case 13: return 'd'; case 14: return 'e'; case 15: return '#'; default: return 0; met vriendelijke groeten, Joeri van Dooren ----- "Rennes Neps" <Rennes.Neps at norby.ee> schreef: > > As I'm not very strong in C, can you please point me in the right direction, what am I looking for there in the file?

I'm trying to send special characters out to ss7 link, but libss7 seems to convert them to zeroes. The challenge is that our service provider demands some of the regional numbers to be sent in format D0+number. When I use D in front of the number in dialplan, libss7 replaces it with 00, So I have a dial string: exten => _[A-Z].,1,Dial(DAHDI/g1/DD0501,,g) But in SS7 trace I see: --VARIABLE LENGTH PARMS[1]-- Called Party Number: Nature of address: 3 NI: 0 Numbering plan: 1 Address signals: 000000501# [ 07 03 10 00 00 00 05 f1 ] Do you have any idea how to fix that?
