I have been running a Production and Test Asterisk in Parallel for 2 years now. My Production box is a Dell Poweredge 1650 using a TDM410 and my Test box is a 1550 with a TDM400. Two weeks ago the production machine decided to drop it’s RAID array and apparently has some power supply/memory issues. I’m running the Test box as production to have service, but Echo is killing me. Can I safely swap the two TDM cards between the 2 archetectures?
Yes. Different drivers for the two cards though, so be aware of that.
