[asterisk-ss7] libss7 problem with dialing a non numeric string

[Rennes Neps]

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;
        }
}

Hei!

 

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?

 

My chan_dahci.conf is as follows:

 

[channels]

switchtype=euroisdn

 

;;; linkset 1

context=incoming_ss7

 

echocancel=yes

echotraining=yes

echocancelwhenbridged=yes

 

group=1

ss7_calling_nai=dynamic

 

;ISDN call type

ss7_internationalprefix = 00

;ss7_nationalprefix =

;ss7_subscriberprefix =

;ss7_unknownprefix = DD

 

cicbeginswith = 2

channel = 2-31

sigchan=1

 

 

Thanks in advance
