Hi,

Simple quick question:

Looking to upgrade to unifi lately

If I want to maintain my existing fixed phone line, as my mom uses it a lot. I pay for a new line, then I merge both lines together am I right? What would be the costs to so this? And any monthly fees?

You mean your phone line? If it is phone line, you cant merge two lines into one phone. It will not work and may destroy your stuffs.

It would be okay for one number with many many ports but it would not be okay with two number with any amount of telephone ports. By the way, UniFi uses Fiber optic cable to deliver internet to your house, not phone line. And after the phone line would be plugged to your modem.

UniFi: Fiber optic cable-> ONU(modem)-> Router\Phone

Normal Phone Line: Telephone pole -> House phone ports

When the signal is converted from UniFi to phone, it will be the same as a normal phone line signal. When they both meet, they will start to cause conflicts. Just imagine there's a bridge for one person only and how can you ask two person to walk together? It is imposiible no matter how much money you have to ask the installer to do this.
