I wouldn't say "make sure", I'd say it's probably better to have a
symmetrical connection at all Asterisk points, however if you're using
a low-bandwidth codec, you can get away with asymmetrical just fine
(and traffic shaping if it's a busy network). I connect my Asterisk
box on a asymmetrical connection to another Asterisk box with the same
type of connection (512/128 - each box in different continents) and I
don't experience major problems, granted I do VoIP packet prioritizing
but it just proves the [a]symmetrical aspect is not an issue.
Yes I should have phrased that better. I use GSM as the codec and that
is a bandwidth hog. The problem is that the really tight codecs are all
proprietory.
That is, at least, in my experience. Also, the dialplan is not THAT
hard to work out, just takes a little reading of how it works, reading
how other people's dialplans work and experimenting. Great source of
info is the popular:

I started experimenting with Asterisk way before I got my hands on a
ISDN card. Back then I started playing with dialplans, how to make
menu's, wake-up call service (that I still use today!) and stuff like
that. It's good fun. If you know Perl, writing AGI scripts provides
endless posibilities.
I am playing with PSTN cards and that is harder, mainly because of the
echo. Yes, I too have a wake up call service using call scripts.
From what I've heard, the new Asterisk to be released in the near
future provides a complete rewrite of the dialplan system and it's
supposed to be much better, together with many new features.
Haven't heard about the rewrite - I will check that out. I don't
subscribe to the Asterisk mailing list because it's just too noisy,
which is a strong indication of the interest, but there are a lot of
posts from ppl who have plainly not RTFM...
HTH.
Cheers,
