Hello, I am trying to use chan_ss7 for 2 servers, each with 4 E1s connected to 2 STPs (one STP per server), with the first E1 on each server containing the signalling link. The servers will share the same point code. I want the 2 signalling channels to provide redundancy, and for each asterisk server to handle calls on the 4 E1s attached to the server. Will the following ss7.conf work if I run mtp3d on both servers? BTW, from the config.c code, it looks like the stp and dpc parameters both store the spc to the link->dpc variable, so are they the same? Server1 SPC: 0x01 --> STP1 SPC: 0x02 Server2 SPC: 0x01 --> STP1 SPC: 0x03 Thank you, Stephen ---------------------------- [linkset-stp1] enabled => yes enable_st => no use_connect => yes hunting_policy => even_mru context => ss7 language => en t35 => 15000,timeout subservice => auto variant => ITU [linkset-stp2] enabled => yes enable_st => no use_connect => yes hunting_policy => even_mru context => ss7 language => en t35 => 15000,timeout subservice => auto variant => ITU [link-stp1_1] linkset => stp1 channels => 1-15,17-31 schannel => 16 at server1:12000 firstcic => 1 enabled => yes [link-stp1_2] linkset => stp1 channels => 1-31 schannel => firstcic => 33 enabled => yes [link-stp1_3] linkset => stp1 channels => 1-31 schannel => firstcic => 65 enabled => yes [link-stp1_4] linkset => stp1 channels => 1-31 schannel => firstcic => 97 enabled => yes [link-stp2_1] linkset => stp2 channels => 1-15,17-31 schannel => 16 at server2:12000 firstcic => 1 enabled => yes [link-stp2_2] linkset => stp2 channels => 1-31 schannel => firstcic => 33 enabled => yes [link-stp2_3] linkset => stp2 channels => 1-31 schannel => firstcic => 65 enabled => yes [link-stp2_4] linkset => stp2 channels => 1-31 schannel => firstcic => 97 enabled => yes [host-server1] enabled => yes default_linkset => stp1 opc => 0x87b dpc => stp1:0x7E7,stp2:0x801 links => stp1_1:1,stp1_2:2,stp1_3:3,stp1_4:4 if-1 => 203.144.65.15 [host-server2] enabled => yes default_linkset => stp2 opc => 0x87b dpc => stp2:0x801,stp1:0x7E7 links => stp2_1:1,stp2_2:2,stp2_3:3,stp2_4:4 if-1 => 203.144.65.16
