[Asterisk-Users] OT: BRI ISDN question

[Iain Stevenson]

... but then you need an ISDN card that supports the CAPI interface. 
Personally, I wouldn't like to spend money on ISDN on the offchance that a 
driver that's under development will remedy the latency (and echo) issues. 
Best to wait for some feedback from a selection of users.
