<p style="MARGIN: 0cm 0cm 0pt"><font face="Calibri">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.

<p style="MARGIN: 0cm 0cm 0pt"><font face="Calibri">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:
