[asterisk-users] considering purchasing a t1 card, any recommendations?

[Zoa]

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.
