Works Well
Purchased the dual-T1 w/EC unit and have been running it for about a month. There were some initial timing problems but those got sorted out and the unit was been running 24/7 since. It is installed in front of an Asterisk High-Availability setup and failover works as advertised. This is the perfect unit to detach TDM processing from a dedicated PCI card in HA situations. It is a little more pricey than a dual T1/E1 card but I still recommend it instead... even if you aren't running HA, because you never know when you'll want to go HA. For any serious business system, I think this unit and an HA setup is a must-have.

Setup was a breeze though the documentation isn't clear on a couple of things. For example, the unit will forget its settings on power-down unless you run "fonulator --write-config" from the master server. This little feature isn't documented and I had to complain to tech support to find out about it. You'll also want to check the firmware and make sure it is the latest and greatest. They are actively developing this system so newer firmware may be available.

Tech Support has been a great help. They were very responsive while we worked through the early timing problem and always willing to provide answers and suggestions... even when it didn't directly relate to their product.

Overall, I think any Asterisk system with T1/E1 should be using this unit instead of the PCI cards. (Sorry Rhino, Digium, Sangoma, etc)
