Hello list, I have 2 ss7 links for the same linkset connected on ports 1 and 3 of my sangoma card. I have declared the following on my /etc/dahdi/ system.conf: #Sangoma A104 port 1 [slot:4 bus:3 span:1] <wanpipe1> span=1,0,0,ccs,hdb3 bchan=1-31 #Sangoma A104 port 3 [slot:4 bus:3 span:3] <wanpipe3> span=3,0,0,ccs,hdb3 bchan=63-93 My configuration is like this: - wanpipe1 : signaling + 30 voice channels (cic 1 to 30) - wanpipe3 : 31 voice channels (cic 31 to 61) How can I tell the chan_ss7 module to use the ports 1 and 3 of my card ? Here is my ss7.conf: [linkset-ls1] enabled => yes enable_st => no use_connect => no hunting_policy => seq_htl context => ss7 t35 => 15000,timeout subservice => auto variant => ITU [link-l1] linkset => ls1 channels => 2-31 schannel => 1 firstcic => 0 sltm => no sls => 1 enabled => yes [link-l2] linkset => ls1 schannel => channels => 1-31 firstcic => 31 sltm => no sls => 1 enabled => yes [host-sang01] enabled => yes opc => 3555 dpc => ls1:3111 links => l1:1,l2:2 globaltitle => 0x00, 0x03, 0x01, 7773 ssn => 7 I guess there is something to do with the "links" parameter but I don't know how to use it. This config works fine for the first link but all channels on the second link appears as "BLOCKED Remote Maintenance". I have checked, the 2 links are connected physically. Thank you for your help.
