Hi,
 I'm sort of stuck on getting this ss7 link up and running. All I know
about the switch i'm trying to connect to is that it's an Ericsson
over E1 and what the opc/dpc are. I'm using a Sangoma A101, but as far
as I can tell, it's up and running correctly. In ss7linktest it goes
so far as to say --SS7 up--, but then it keeps trying to resend
messages

 Here is the output of my ss7linktest :

Got retransmission request sequence numbers greater than 127.

If I try this in asterisk, all I get is :
Got retransmission request sequence numbers greater than 127.
Retransmitting 4 message(s).
Got retransmission request sequence numbers greater than 127.
Retransmitting 4 message(s).

Here is my conf files:

defaultzone=in

Any help would be greatly appreciated.
