[asterisk-ss7] dahdi, libss7 and asterisk

[Vishnu Kumar D R]

Guys,

The thing is there are no CICs configured on the line.
Since, I will be using it for a USSD application.
I wanted to test if dahdi is recognizing the SS7 links.
The telco has configured 8 links starting from first timer slot.

So, I have configured like this.
system.conf:
# Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER) HDB3/CCS/CRC4
span=1,1,0,ccs,hdb3
bchan = 9-31
mtp2 = 1
mtp2 = 2
mtp2 = 3
mtp2 = 4
mtp2 = 5
mtp2 = 6
mtp2 = 7
mtp2 = 8

 chan_dahdi.conf:
[channels]
#include /etc/asterisk/dahdi-channels.conf
usecallerid=yes
callwaiting=yes
restrictcid=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
group=1
callgroup=1
pickupgroup=1
ss7type = itu
ss7_called_nai=national
ss7_calling_nai=national
ss7_explictacm=yes
linkset = 1
pointcode = 1234
adjpointcode = 4321
defaultdpc = 4321
sigchan = 1
cicbeginswith = 1
channels = 9-31
networkindicator=national

dahdi-channels.conf
; Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER) HDB3/CCS/CRC4
group=0,11
signalling = ss7
group = 63

I get the error:
ivrs-second*CLI> module load chan_dahdi.so
Unable to load module chan_dahdi.so
Command 'module load chan_dahdi.so' failed.
