I'd like to notice that I have LIBSS7+Domjan patches working 
for me in production (light load) for a month now. Will try 
updated versions soon. Thank you Domjan and Matt for such a 
great stuff.

> blocked state when bringing
> ; the links up for the first time.

> ;ss7_initialhwblo=yes

> ; This option is whether or not to trust the remote echo
> control indication.  This means
> ; that in cases where echo control is reported by the
> remote end, we will trust them and
> ; not enable echo cancellation on the call.
> ;
> ;ss7_use_echocontrol=yes
> ;
> ; This option is to set what our echo control indication
> is to the other end.  Set to
> ; yes to indicate that we are using echo cancellation or
> no if we are not. ;
> ;ss7_default_echocontrol=yes
> ;
> ; This sets the number of binary places to shift the CIC

> ;sls_shift=0

> ; Set this option if you wish to send an INR request if
> no calling party number is specified.
> ; This will attempt to tell the other end to send it

> ;inr_if_no_calling=yes

> He also added a number of CLI commands and enhanced
