Thanks Riman, can I use it as ATA adapter (FXS) only?

Currently I am looking for FXS adapter that defenetly works with my IPX Office. I need to use it for my Polycom star conferece phone.
I'd been trying using ATA186 also SPA 2100, both are not working properly over the network. I'd been trying to figure out to make it works for long and looks I gave up.
Tadiran USA support didn't help and they keep push me to contact their vendor/authorized dealer. Basically they aren't let me do by my self.

Thanks
