I have a multiline phone in my office - 1 is for home phone, 1 for the business line.
To answer a call, you have to press ACCEPT on the MagicJack console, and then quickly press the business line (line 3 at my house) to pick up the call. Then there is a small delay, but enough to make it sound weird to the caller.
Not enough weird to make a difference, but weird.
It’s ungainly.
I looked at Ooma too - expensive at triple MJ prices, and then you have to add their LINX thing so that you can use multiple home extensions (should you want it to replace, say, Comcast).
Still, with the equipment cost, Ooma is cheaper than Comcast or Verizon Home.
Ooma business charges a monthly fee of $20. Don’t see the reason for it since the technology is identical and the service is in the logic they sold you in the box.
I’d be looking for something better than MJ, but less expensive and obtrusive than Ooma. Not sure what else is out there.
