[asterisk-ss7] Problems with chan_ss7-0.8.4

[Marcelo Pacheco]

Have you run an ISDN link on the same hardware before ? Any HDLC Abort
errors back then ?

I jumped chan_ss7 when I heard of HARDHDLC (hardware HDLC), I'm using it
now and all my HDLC Abort errors are gone.

I strongly sugest the chan_ss7 people to go back to using Digium HDLC
support so we can use HARDHDLC.

Just my $0.02.
