No, not at all.  HDLC blips are certainly nothing to be terribly 
concerned about.  In MTP2, there is a measurement done on the rate of 
them coming in the form of a "leaky bucket" error rate monitor.  A 
certain error rate threshold has to be exceeded before it reports a 
problem to MTP3.  I don't think we have any problems even with software 
HDLC with exceeding this threshold.  Also, MTP2 is designed to be able 
to retransmit any MSUs that have been received in error.  Certainly no 
more than chan_ss7 might experience in comparison.

Echo cancellation is always a useful thing.  It really depends on your 
setup, but if you're doing SS7, you probably want some decent echo 
cancellation "Just in case".

I've done all my testing and development for libss7 on Digium boards.  
Obviously I'm a bit biased since I work for Digium, but I think that 
since I'm very familiar with how they work, I can make it run better 
through additional driver work and so forth.
