[Asterisk-Users] Dell SC420 and Interrupts

[Joe McConnaughey]

The SC420 does not support APIC (at least not with current BIOS).  The 
Digium TDM400B card seems to always seek the same IRQ so it locks one down. 
The clone X100P cards often get a shared IRQ, even if vacant ones are 
available.  I've found both the Digium card and the clones very frustrating 
with this system.  Thus the reason Digium does not recommend it.  I've gone 
to a mostly SIP configuration using Sipura SPA 3000's.

For analog stations, I got an Efficient Networks SB510 (H323 protocol) on 
EBay but it doesn't work very well.  Caller ID is incomplete between it and 
the Asterisk for inbound and outbound calls.  (No caller-id time transmitted 
to phone, only number sent and a default "SB510" for the name on each port. 
Inbound calls from the Asterisk to the SB510 just say "Asterisk" and the 
extension number.  This unit also does not support caller-id/calls-waiting, 
switchook flash or many POTS like features you'd want.  The SPA2000 and 
SPA3000 seem to work better than anything else.

If the SC420 is sharing interrupts, can you go around that by chaning slots
or maybe, I don't know if it can do APIC? Or how about disabled the shared
devie like USB?

|The cheap ones on EBay won't work with the SC420 server.  I
