[asterisk-users] Trouble configuring TDM400P on Dell SC420

[Devraj Mukherjee]

Hi Everyone,

I am running Asterisk 1.2.7 Zaptel 1.2.5 on CentOS 4.3 on a Dell
PowerEdge SC420. I was running an older version of Asterisk (can't
remember what, but was using the wcfxs kernel module) under Gentoo
Linux and succsessfully had Asterisk talking to my TDM400P card.

However on my CentOS installation and Asterisk upgrade the TDM400P has
stopped responding, /dev/zap channels dont get created. I have
gathered that there is an incompatibility with SC 420 server hardware
and TDM400P (http://www.digium.com/en/docs/misc/compatibility_notes.php)

Has anyone had similar issues, is there a work around?
