Hi, I'm using two asterisk-1.2 with chan_ss7-0.8.4 connected to an MSC. There is something strange here. my ss7.conf is here [linkset-ser] enabled => yes enable_st => no use_connect => no hunting_policy => odd_lru subservice => national context => ss7 language => es [link-0] linkset => ser channels => 1-15,17-31 schannel => 16 firstcic => 1 enabled => yes [link-1] linkset => ser channels => 1-15,17-31 schannel => 16 firstcic => 33 enabled => yes [link-2] linkset => ser channels => 1-31 schannel => firstcic => 65 enabled => yes [link-3] linkset => ser channels => 1-31 schannel => firstcic => 97 enabled => yes [link-4] linkset => ser channels => 1-31 schannel => firstcic => 129 enabled => yes [link-5] linkset => ser channels => 1-31 schannel => firstcic => 161 enabled => yes [link-6] linkset => ser channels => 1-31 schannel => firstcic => 193 enabled => yes [link-7] linkset => ser channels => 1-31 schannel => firstcic => 225 enabled => yes [link-8] linkset => ser channels => 1-31 schannel => firstcic => 257 enabled => yes [link-9] linkset => ser channels => 1-31 schannel => firstcic => 289 enabled => yes [link-10] linkset => ser channels => 1-31 schannel => firstcic => 321 enabled => yes [link-11] linkset => ser channels => 1-31 schannel => firstcic => 353 enabled => yes [host-ser3] enabled => yes default_linkset => ser opc => 0x491 dpc => ser:0x48a if-1 => 73.24.30.63 links => 0:1,2:2,4:3,6:4,8:5,9:6,10:7,11:8 [host-ser2] enabled => yes default_linkset => ser opc => 0x491 dpc => rbt:0x48a if-1 => 73.24.30.62 links => 1:1,3:2,5:3,7:4 [cluster] ; Listen on TCP port 5040 port => 5040 0 => ser2#if-1 1 => ser3#if-1 2 => ser2#if-1 3 => ser3#if-1 4 => ser2#if-1 5 => ser3#if-1 6 => ser2#if-1 7 => ser3#if-1 8 => ser2#if-1 9 => ser2#if-1 10 => ser2#if-1 11 => ser2#if-1 The problem is, whenI do a ss7 cluster status I see on the host "ser3": ser3*CLI>ss7 cluster status sender ser2, addr 68.197.20.0, state alive, last 16 msec, up 1, down 0 receiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try 16 msec, 1 fails, 543 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 1 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 1 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 1 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 1 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 1 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 15 fails, 0 forwardsreceiver ser2 if 1, addr 73.24.30.62, c:connected, p:, last try428 msec, 15 fails, 0 forwards And, on host "ser2" ser2*CLI>ss7 cluster status sender ser3, addr 240.15.38.0, state alive, last 245 msec, up 1, down 0 receiver ser3 if 1, addr 73.24.30.63, c:connected, p:, last try 327 msec, 0 fails, 20 forwardsreceiver ser3 if 1, addr 73.24.30.63, c:connected, p:, last try210 msec, 0 fails, 15 forwardsreceiver ser3 if 1, addr 73.24.30.63, c:connected, p:, last try210 msec, 0 fails, 240 forwardsreceiver ser3 if 1, addr 73.24.30.63, c:connected, p:, last try102 msec, 0 fails, 282 forwards I just have modified the MAX_CIC from 256 to 512.
