Disto Question

I happen to have an older 64Bit machine and the ability to use it as a PBX. Is there any reason I should be going with the 32bit version instead? Also, is higher better in the case of versions? Should I grab the top one and just be done with it?

I am driving a Digium analog card. TDM400P.

You are best off using the latest distro.

Good to know! Thanks! Will the 64bit version support my analog card? TMD2400P

Yes it will support it.
