100 E1 should work with 2 signalling links, as long you don't have to many
But, 100 / 7 ~= 15 E1 per box, i think its too much. try to narrow down
some 'years' ago i've faced similar problem, and well used TDM gateway with
many E1s and DSP on board. Price level of such gateways is when comparing to
25 Digium's TE400P + 25 good servers, at least power consumption beats you.

Anyway, the chan_ss7 is comericial product from Dicea, you could obtain help
try simple think, is debian a host name put in /etc/hosts?
is a port 12000 realy open?
mtp3_connect_socket: Could not connect to hostname/IP address 'debian', port
ssh to host debian, and run netstat, why you bring firewall level & nmap
when you are not sure if some process is really running on that host and it
has opened a tcp socket?

the log:

Apr 30 03:22:35 [ERROR] mtp3io.c:84 setup_socket Cannot bind receiver
socket, errno=98: Address already in use

really says that shometing has already used this port, so netstat -a -n |
grep 12000 for a start, ok?
