I saw the single port Patton FXS which got my hopes up, but same as you, I didn't see an FXO. Sent via BlackBerry from T-Mobile

If the power is off it doesn't do any good, that's the only reason the relay is appealing. You can have an old school POTS phone someplace and it won't do anything unless the power is out; as i recall you can make the 3102 pull the relays (either virtually or for real) if it can't register on the FXS side. Don't take any of this as a ringing (heh) endorsement for the SPA 3102. I wasted many many hours of my life on the POS and found that Cisco completely abandoned it. I would never spend money on any unit in that product line w/o a gun to my head. I wouldn't be surprised if the FXO+FXS pattons have the relays too (I know the audiocodes I had for a while did). Patton makes a small one port FXS for $75 or so but I didn't see an FXO flavor (just the 2 port smartnodes). They are at least 3-4x as much as an SPA3102 and don't get you the relay failover (but they do actually work for inbound calls which is a big plus :) ). -Eric On Feb 6, 2010, at 3:51 PM, Tony Graziano wrote: > The patton will allow a phone to register to it directly as a secondary > line.
