Unfortunately i didn't save it, so will need to repeat it on monday, but when
i looked at the debug it was that the other side is sending blocking request
for CIC 1 with range 30 and 'ss7 show cics' shown 17 as idle. At this time
there was a call on CIC 31 (marked as remotely blocked), which was not
interrupted until the other side have sent GRS with the same CIC and range

here is the ss7 related part located at the end of the chan_dahdi.conf :

signalling=ss7
ss7_called_nai=dynamic
ss7_calling_nai=dynamic
ss7_internationalprefix=00
ss7_nationalprefix=0
linkset=1
networkindicator=national
group=1
callgroup=1
pickupgroup=1
context=Span1
ss7type=itu
pointcode=X
adjpointcode=Y
defaultdpc=Z
cicbeginswith=1
channel => 1-15
cicbeginswith=17
channel => 17-31
sigchan=16
#include ss7.timers

the adjpointcode is different from the defaultdpc and the included file is
with the default timers listed earlier in the config.

and the system.conf content:

# Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER)
span=1,1,0,ccs,hdb3,crc4
bchan=1-15,17-31
#dchan=16
mtp2=16
alaw=1-15,17-31
#echocanceller=mg2,1-15,17-31

# ready for PRI ... change signaling if SS7
# Span 2: TE2/0/2 "T2XXP (PCI) Card 0 Span 2"
span=2,0,0,ccs,hdb3,crc4
bchan=32-46,48-62
dchan=47
alaw=32-46,48-62
#echocanceller=mg2,32-46,48-62

loadzone = bg
defaultzone=bg
