Matt,

	It is obvious that Asterisk/TDM support from Sangoma is (and has been) 
secondary.  Their cards support data like no other.  Excellent.  Voice, 
on the other hand, appears to be immature.

	Digium cards work less well with data.  One of my systems cores/hangs 
%40 of the time when I try to tweak HDLC/CHDLC zap channels. Data being 
an afterthought for Digium, obviously...

	But this being the asterisk-users list, I think the Digium cards are 
better at this point for voice (Asterisk).
