Wow, this is a completely neutral and very valuable review. Thanks a lot
Zoa.
I´m an * newbie; my little box will only needs 20 extensions to give
termination to remote users and I´m about to buy a PRI interface; I
decide to get Sangoma hardware.. a lot of people recommended it to me.
In you review you said: "The biggest choice you need to make is if you
want onboard echo cancellation or not". How can I really know if I will
need echo cancellation? I´m planning to get a single span card (which
doesn´t include echo cancellation) but how can I know if I really need
this feature??
Thanks in advance.

I think the recent Digium and Sangoma cards are quite similar. (and
about the same price)
I didn't try sangoma so far, never had any issues with the digium
cards, I have no clue how the digium helpdesk is, i never needed to
call them.
(well not really correct i did call them once, years ago for a
firmware problem with their first te410p revision, causing a crash
once every few months they had the distributor send me replacement
cards right away, before i returned the old ones, so that i could swap
them without having to shut down the server for a week).
Configuration and installation for the cards is pretty
straightforward, all you need to do is compile the kernel modules for
your kernel.
I personally installed at least 20 digium pri cards, all on different
hardware without problems related to the digium hardware. (sometimes i
did have bad cables, bad pri's, oh and my embedded pc didn't provide
enough power for FXO ports).
You will probably find more people on the list with problems with
digium than people with problems with sangoma. This might be because a
lot more people seem to use the digium cards with asterisk than
sangoma cards with asterisk. (Based on the people i speak to, i'd
guess 1 to 5% use sangoma?).
The biggest choice you need to make is if you want onboard echo
cancellation or not, you might not need it and if you want it its
going to cost you a lot more than without. (both for sangoma and
digium hardware). - They both seem to use exactly the same Octasic
echo cancellation module.
If you need on board echo cancellation but don't need 4 ports, digium
is the only choice with their 2 port card with Octasic echo
cancellation module.
(Afaik sangoma doesn't have such a 2 port board with on board E.C. but
i could be wrong.)
Btw, there are more options, dialogic has compatible cards and so does
eicon. (you will need deeper pockets though, the eicon retails at +/-
12000 euro for a quad span i think - people who buy these for asterisk
usually do so for hardware faxing or interconnection to different
carriers at the same time.)
Some people prefer digium over sangoma because they sponsor the
asterisk development that way. I'm not one of them, i buy digium
cards (or tell my customers to buy them) because i'm happy with their
product.
Dislaimer: I know some of the people within Digium quite well, so
maybe i get exceptional support or they ship me handpicked gold
plated, overclocked versions of their cards (not really since i just
buy them from a reseller).
Cheers,
Zoa.

I would have to second the Sangoma buy. Their tech support
is second to none and more then helpful.
I've never had any problems with their products
that wasn't
my own fault.
Thirded - I've just done another install with a Sangoma A102 -
the setup guides you through all the way and takes no more
than 30 minutes (Including recompiling zaptel, which it does
for you)
