[asterisk-ss7] libss7 woes!

Hi

I am using Sangoma cards :(
I know I should have used Digium but now the custom has these cards and I
have to make them work with SS7 :(

Unable to receive incoming calls on chan_ss7, I have decided to give another
shot to libss7

Could someone please share their configuration of dahdi/system.conf,
chan_dahdi.conf, wanpipeX.conf with me for multiple signalling links ?

I am especially confusing with the numbering schemes of CICs and signalling
channels. I have signalling links on the first 2 spans, on 16th channel
each.

So , how do I number after the 2nd channel onwards.
Is it 32-64
or 31-63
or what ?
:)

My current config is
