This is a bit tricky...
First of all, I had Vonage VOIP... but while the price was right, and most calls came through clearly, there were some times when bits and pieces of conversation were dropped. So... why not give MagicJack a try.
Gawd! don't even think of it... Google "Magic Jack Beeps" and you'll see why.
So after transferring my home Voip phone to Magic Jack, I have now (after 4 hours in chat w/MJ changed my number back to Vonage.
Thus the question... How does call forwarding really work? Not the mechanics of setting it up on the phone, but what actually happens to the signal. So... one ring, the call forwarding comes in... Does the signal go through the home phone, and then to another home phone, (or in my case... a cell phone) .. or is the does the signal go directly from the caller's phone, to my cell phone.
Two reasons for asking...
1. If I am not at home for a period of time, the Vonage modem would be connected to my internet provider. I would prefer not to keep the phone connected, but let the modem respond and just forward the calls.
2. On some occasions, for no apparent reason, the Voip phone quality is poor, and automatic forwarding to the cell would be a good option, IF the caller's connection is direct to the cell.
Yeah... weird... why not do Comcast or AT&T wired... yeah... check the cost, and then the problem of moving to Florida for months at a time. Connect, Disconnect, Vacation Hold, Number forwarding... and Comcast in Illinois does not know that Comcast in Florida even exists.
I'm too old for this shtuff.
