Hi, So today I started getting to know chan_ss7. The issue is I want to test chan_ss7, but I only have 1 Asterisk box and 1 4-port Diiagium E1 card. I want to know, and please understand my ignorance of ss7 :), if I only have 1 box, with a Digium 4 port E1 card, and I want to dial out on port1 and recieve the call on port2, do I configure two links with one linkset, or two seperate linksets (I am following the templates) Also, with the above config, is this correct: [link-l1] linkset => outgoing1 channels => 1-15,17-31 schannel => 16 firstcic => 1 enabled => yes [link-l2] linkset => incoming2 channels => 1-15,17-31 schannel => 16 firstcic => 32 enabled => yes is my channels labled correctly? -- thanks, Yusuf -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
