IP Voice and PVDM's will cost you.... you could look at 3rd party PVDM to see the cost. IP Voice will be a few hundred dollars<div><br></div><div>an 881 would probably work if you have a switch.... only 2 Ports are PoE. and a single FXO should work if you're only using it for E911. But it's >$1000 and you have two external power bricks too.</div>

<div>3. Can I use something like a VG202 or something to route the E911 calls out, and just hope we never have a WAN failure? (It's only staffed two days a week, with 3 people max)</div>
