I'm putting together an Asterisk system that if successful I will roll out in a couple of offices. I'm planning on using the TDM400P cards from Digium. (They are not purchased yet so I'm also open to suggestions of best places to buy them.) Does anyone have experience with systems that are robust enough I could use them for high availability? The other side of this is if anyone knows of systems I should avoid. Up to now I have been doing all my testing on a cheap white box PC that I wouldn't want to put into a production environment. I've done a fair bit of searching online about this but I'd like to just make sure before purchasing.
Thanks in advance, Ray
