I searched the list, came up with a few references to the NETspider-U, but no conclusions. I'm looking for a single channel ISDN BRI-U card.

Hi,
I've been browsing for FXO devices, and I'm really surprised at their costs. Why such devices are so expensive and somehow hard to get ?
Because most people that would need the items can quickly scale beyond
analog incoming lines. So there is not a glut of them on Ebay to drive
the prices down.
Also FXO devices require certification to be used in many countries, and this is not cheap, the manufacturer has to pass this cost on to someone.
But if you want 24 or 30 lines, a Digium Wildcard T100P/E100P is only $25/$20 per line or for 96/120 lines, a T400P/E400P is only $16/$13 per line.
For smaller systems, you'd have to go a NetJet ISDN BRI card ($150? for two lines) or X100P ($100?) per 1 line, or VoiceTronix OpenLine4 ($500?), OpenSwitch 6/12 ($800/$1500?) for 4/6/12 analogue lines.
The openswitch cards can operate groups of the ports as FXS ports too.
cheers, Woody
