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. ------------------------------ Message: 12 Date: Mon, 1 Aug 2005 21:13:30 -0500 From: "Anton Krall" <akrall-lists@intruder.com.mx> Subject: RE: [Asterisk-Users] Re: Asterisk-Users Digest, Vol 12, Issue 171 To: "'Asterisk Users Mailing List - Non-Commercial Discussion'" <asterisk-users@lists.digium.com> Message-ID: <20050802021816.8D1795B40F6@intruder.com.mx> Content-Type: text/plain; charset="us-ascii" 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? |-----Original Message----- |From: asterisk-users-bounces@lists.digium.com |[mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of |Joe McConnaughey |Sent: Lunes, 25 de Julio de 2005 12:48 p.m. |To: asterisk-users@lists.digium.com |Subject: [Asterisk-Users] Re: Asterisk-Users Digest, Vol 12, Issue 171 | |The cheap ones on EBay won't work with the SC420 server.
