Hi
Thank you for reply.
for simulating a real PSTN network scenario I still need to have 2 point code in asterisk and one signaling link for them.
In existing libss7 ,if we have 2 signaling links on 2 linksets with 2 opc for Asterisk there is no problem.
I looked at source of libss7 I saw in mtp3.c:( with my limited programming knowledge)
if (ss7->pc != rl.dpc) {
ss7_error(ss7, "Received message destined for point code 0x%x, but we are 0x%x. Dropping\n", rl.dpc, ss7->pc);
....
switch (userpart) {
case SIG_ISUP:
if (link->adj_sp->state == MTP3_UP) {
return isup_receive(ss7, link, &rl, sif + rlsize, siflen - rlsize);
so it seems for every linkset there is a "struct ss7", and if we can query existing list of "struct ss7"s(linksets) and find
matching ss7->pc with received MSU point code, we can put correct address of "struct ss7" in "isup_receive()" function
and send the call to it's appropriate linkset.
according to my grep libss7 allocate new "struct ss7" with *ss7_new(int switchtype) function but I cannot find where
libss7 call this function and where is list of allocated "struct ss7"= linksets
Do you agree with me and could you please help me ?

Hi,
Asterisk (with libss7) is a signaling end-point, so you
can't have two
point-codes - you need an STP (which Asterisk is not)
between the two
boxes in order to separate the two signaling channels.
However you do not need two point-codes for this setup, but
simply to
define two groups of channels ... from the example in my
previous email,
change the linkset definitions to:
linkset=1
networkindicator=national
group=1
context=From_Span1
pointcode=1
defaultdpc=2
adjpointcode=2
cicbeginswith=1
channel => 1-15
group=2
context=From_Span2
cicbeginswith=17
channel => 17-31
sigchan=16
#include ss7.timers
linkset=2
networkindicator=national
group=3
context=From_Span3
pointcode=2
defaultdpc=1
adjpointcode=1
cicbeginswith=1
channel => 32-46
group=4
context=From_Span4
cicbeginswith=17
channel => 48-62
sigchan=47
#include ss7.timers
Now you have 4 groups on the same 2 linksets, which is equal
of having
two separate linksets on the same signalling link.
