Hi all. Im very new to the SS7 protocol and i need your help. This is thje problem: We have one system with 8 PRI in SS7. In this system one of the pri is the one that take the signal on channel 16. Now we wan to put another system with two pris that shared the signal with the first one via mtp3d. In the first system, we start mpt3d, start asterisk and the pris of this machine goes up with no problems but in the second one we start asterisk and the pris never goes up. We get this error on the asterisk console " Invalid hostname XXXX or port 12000..........". The hostname are correct and if i try to telnet XXXX 12000 y connect fine. Any Ideas?. This is my config on the two systems [linkset-siuc] enabled => yes enable_st => no use_connect => yes hunting_policy => even_mru context => e1-incoming language => es subservice => national variant => ITU t35 => 15000,timeout [link-l3] linkset => siuc channels => 1-15,17-31 schannel => 16,host1:12000 firstcic => 1 enabled => yes [link-l1] linkset => siuc channels => 1-31 schannel => firstcic => 257 enabled => yes [link-l2] linkset => siuc channels => 1-31 schannel => firstcic => 193 enabled => yes [link-l5] linkset => siuc channels => 1-31 schannel => firstcic => 225 enabled => yes [link-l4] linkset => siuc channels => 1-31 schannel => firstcic => 65 enabled => yes [link-l7] linkset => siuc channels => 1-31 schannel => firstcic => 33 enabled => yes [link-l8] linkset => siuc channels => 1-31 schannel => firstcic => 97 enabled => yes [link-l6] linkset => siuc channels => 1-31 schannel => firstcic => 129 enabled => yes [link-l9] linkset => siuc channels => 1-31 schannel => firstcic => 161 enabled => yes [host-host1] enabled => yes opc => 16373 dpc => siuc:2028,l3:2040 links => l3:3,l4:4,l7:7,l8:8,l2:2,l5:5,l1:1,l6:6 if-1 => 10.0.1.1 [host-host2] enabled => yes opc => 16373 dpc => siuc:2028,l3:2040 links => l9:1 if-1 => 10.0.1.2 -------------- next part -------------- An HTML attachment was scrubbed...
