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? Tried to look already, but unexperienced eye did’nt find it :D 



Thanks

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 

linkset=1 

signalling=ss7 

ss7type=itu 

pointcode=50 

adjpointcode=14 

defaultdpc=14 



;networkindicator=international 

networkindicator=national_spare 

ss7_called_nai=dynamic 

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
