RE: [asterisk-users] A question on ISDN cards... (in the UK)

2006-11-15 Thread Senad Jordanovic

 Would anyone like to recommend a good and reasonable quality ISDN
 card for use in the UK, as after a lot of good results with TDM400P
 cards with several systems installed now, I need to look at a few
 ISDN BRI (old business highway about to move to ISDN2) and possibly a
 single-line PRI (ISDN-30) system.   
 
 Many thanks,
 

For low cost 1 port:

For 4 ports, try:
http://www.bicomsystems.com/products/C/P/319/282/

We also have just done some tests with new Digium BRI card which is
promising since it has echo cancellation on board.

Some other people use CAPI cards so you may want to look at that too...

I'd say the most important distinction is the choice between HFC based
ISDN cards (starting around £9) and active cards, like Diva, Digium etc
(~£300).

Whilst the HFC cards work (with bristuff) you need to be prepared to
reload modules regularly and go through other hoops.
I used to work in a IT company, and there it's perfectly allright to use
cheap cards, because the skills to reset modules etc are available at
all times.
For a clients' system I wouldn't go down that route and spend the money.
I have no complains on call quality or dropped calls on cheap cards nor
on expensive cards, it's the administration and 'shinyness of the
product'.

 There seems to be a plethora of different ISDN cards available in both the
 BRI and PRI range - all with varying prices too - from ?25 to nearly ?1000
 from some popular reseller sites...
 Does anyone have (or know of) a good comparison site, or have views on one
 card type over another?
 I'm assuming that the more expensive cards have additional features like
 better echo cancellation and audio processing abilities (or less CPU
 overhead?)

Remember that ISDN may not be ISDN (well it is), but you specifically
need ISDN2e for BRI and make sure a PRI is configured as EuroISDN (ISDN
v110, the UK default is v85).
