Hi, Right. The ss7.conf file of my "telco side" equipment doesn't include the [cluster] section. One detail: I can see by your ss7.conf that you configured 2 linksets, one for each link. I tried this at first, but could not make the cluster work. So, I'm using just one linkset for the 2 links, considering the 2 boxes in the cluster as one "virtual" server. This is my config file for the "telco side" box: [linkset-siuc] enabled => yes enable_st => no use_connect => no hunting_policy => seq_lth context => default language => da t35 => 15000,timeout subservice => auto [link-l1] linkset => siuc channels => 1-15,17-31 schannel => 16 firstcic => 1 enabled => yes echocancel => no echocan_train => 350 echocan_taps => 128 [link-l2] linkset => siuc channels => 1-5 schannel => firstcic => 33 enabled => yes echocancel => no echocan_train => 350 echocan_taps => 128 [host-AST000010] enabled => yes default_linkset => siuc opc => 0x1 dpc => siuc:0x2 links => l1:1,l2:2 if-1 => 192.168.0.60 Best regards, Patrick -------------- next part -------------- An HTML attachment was scrubbed...
