I would like to setup a small PBX using the Linksys NSLU2. I was thinking of using a couple of PAP2s to get 4 entensions. I would also like to get two FXOs so I can attach a couple of PSTN lines to my PBX. Has anyone here on the list tried the NSLU2 (or a similar low-cost device) for setting up a basic PBX? What kind of performance should I expect from this setup? Any docs available for this? Any other advice? Sukrit.D.
