[asterisk-ss7] a104 libss7 CIC configuration

[Kaloyan Kovachev]

Hi,
the config changes suggested from Michal (in both chan_dahdi.conf and 
system.conf), should also fix your continuity check problems - just ask 
the telco to repeat the test one you made them.

in system.conf you need the same changes:

#Sangoma A104 port 2 [slot:4 bus:4 span:2] <wanpipe2>
span=2,2,0,ccs,hdb3,crc4
bchan=32-62              <<< changed
echocanceller=mg2,32-62  <<< changed

#Sangoma A104 port 3 [slot:4 bus:4 span:3] <wanpipe3>
span=3,3,0,ccs,hdb3,crc4
bchan=63-93              <<< changed
echocanceller=mg2,63-93  <<< changed
#hardhdlc=78

#Sangoma A104 port 4 [slot:4 bus:4 span:4] <wanpipe4>
span=4,4,0,ccs,hdb3,crc4
bchan=94-124              <<< changed
echocanceller=mg2,94-124  <<< changed
#hardhdlc=109
