[asterisk-ss7] ANSI SS7

[Matthew Fredrickson]

It looks like you have a very low level problem on that line.  We are 
sending the other end SIO (To start the alignment, but the other end is 
not going through the alignment process.  The only thing I can think of 
is that either:

A) You don't have your signalling channel setup correctly.  Are you 
using a sangoma card?  I've seen weirdness like this with sangoma 
cards.  The problem was a misconfiguration with the dchannel wanpipe 
setup.  Another possibility is that maybe it's a 56kbps link and you're 
trying to use it in 64kbps mode.

B) The line is not configured at the other end to begin alignment.

I'm suspecting it is probably something along the lines of option A.
