Dear all,
I'm testing the latest release of chan_ss7 (0.9), with 3 asterisk boxes. The
first one (AST001) simulates the telco equipment and has a Digium TE410P,
but for this test we are using just the first 2 spans. The remaining boxes
(AST002 and AST003) receive each one an E1 trunk from AST001, but only the
first E1 (the one that goes to AST002) has a signaling link configured. So
we configured AST002 and AST003 as a cluster.
Everything seems to be fine: all circuits idle, GRA received from both
cluster machines.
Unfortunatelly, the cluster only answers calls if they are placed in the
first 31 circuits, corresponding to the E1 that contains the signaling link.
For any call that attempts to use a CIC >=33, I get the following message:
SS7 channel SS7/555 allocated successfully.
-- Called 555
-- SS7 hangup 'SS7/siuc/33' CIC=33 Cause=27 (state=7)
== Everyone is busy/congested at this time (1:0/0/1)

process_anm: Got ANM message, but no ACM, on CIC=33?!?
On AST003:

ANI= DNI=555 RNI= redirect=no/0 complete=1.

== Spawn extension (default, 555, 2) exited non-zero on 'SS7/siuc/33'
-- SS7 hangup 'SS7/siuc/33' CIC=33 Cause=0 (state=5)
If I configure a signaling link also on the second E1 (the one that connects
to AST003) then everything works.
I took a look at some posts about cluster configuration, and some told that
it was possible to have the signalling link on one server, and have another
server using this link. What am I doing wrong?
Best regards,
Patrick Blackman
