Do you have to have phone company set-up a hunt group for line roll over?

If one line is in use it automatically rolls to the other line for incoming calls and if you just pick up the phone for an outgoing call. No phone company needed!

I have caller id with my phone company...so I am not sure if it would work if you did not have that option.

Yes. You can do 'in line' connection. Connect the line to SENTRY, then connect SENTRY to phone. The downside is your phone will not show the caller id info.

Yes, you can use a fax in one of the lines if you have a different one to use as your phone

Yes. If you have configured a VOIP provider (or several), the device will let you choose what line/account you want to use for outbound calls. Unless you specify a default.Overall a well-designed product. Just be aware that it can't do Wifi; I had to move my Internet router to someplace next to a phone outlet in order to connect the base station.

Nope. As long as you have an analog line you're good to go. You don't need a phone system or anything like that.

No, I don't believe so. Never needed to, but can't find anything in the owner's manual to indicate that call forwarding is a feature. I believe that feature is only available through your phone company.

Yes, up to 5 numbers. You will need a phone line, Internet phone, or in my case, I use GSM (a sim card) via straight talk.

No, you don't need a phone line unless you are going to use the remote calling feature.

It should, but note if using GoogleVoice for your calls it may kick in first. You'll have to set your answering machine to pick up at the 4th ring. GV's pick up time can't be changed/extended.

Yes. You have several choices for the different lines. I have four phone lines and mine are set so each has its own individual ring tone.

You have to call straight talk and have them set it up, but be prepared, b/c it takes a long time and is a bit of a hassle.

I don't know for a fact but I assume not. They would be calling a local number. I believe it works the same as a cell phone would.

That's up to your phone provider not the phones themselves. If its Verizon AT&T; whoever just tell them to set your lines to rollover.

That really depends on the voip system. If it will allow you to set multiple destinations for a single inbound number, i dont see why not.

Yes you can. In fact when you pick up the second line it states you are on a conference call. Hope that helps.

I'm guessing you could, because I chose the plan, it didn't come with the phone. So assuming you would do the same. No harm calling or webchat with AT&T; first.
