In summary, the conversation discusses the use of option A, which provides an always-open-line and no communication problems, and option B, which may work when the ground is the building ground. Liad asks for clarification on what type of phones and power source is being referred to, and explains that using a building ground for the phone line may result in a weaker signal and increased risk of damage from electrical transients. He also mentions that the phones he is using are basic and only require 24V to function properly.

Not sure I understand your question. What kind of phones, and what is the 24V? In the US, the POTS (plain old telephone sets) use -48V for power. And if you are asking if you can use a building ground instead of the 2nd conductor in the twisted pair of phone line, the answer in general would be "not if you want a clear signal". Also, building ground is susceptible to electrical transients (like surges caused by nearby lightning strikes), so the chance of damaging the phones would increase if wired that way.

As for damaging the phones - they wouldn be connected for a long time and I don't really care about them. 
A for noise - as long the line will work and I'll be able to understand what the person in the other end says - I'm ok with it.
The phones are just plain phones, and 24v is enough to get the line open with no noises.

FAQ: Option B: Ensuring Ground Communications in Buildings
What is Option B for ensuring ground communications in buildings?
Option B is a method for establishing reliable ground communications in buildings. It involves using a ground-based antenna system to improve signal strength and ensure consistent communication between devices within a building.
How does Option B work?
Option B works by installing a ground-based antenna system, also known as a Distributed Antenna System (DAS), within a building. This system captures and amplifies signals from external communication sources, such as cell towers, and redistributes them throughout the building to improve connectivity and coverage.
What are the benefits of using Option B for ground communications in buildings?
Option B offers several benefits, including improved signal strength and coverage, reduced signal interference, and enhanced emergency communication capabilities. It also allows for better communication within the building, leading to increased productivity and efficiency.
Are there any limitations to using Option B for ground communications in buildings?
Option B may not be suitable for all buildings, as it requires proper installation and maintenance to ensure optimal performance. Additionally, the effectiveness of the system may vary depending on the building's location and surrounding terrain.
How does Option B compare to other methods for ensuring ground communications in buildings?
Option B is considered to be one of the most effective methods for ensuring ground communications in buildings, as it provides reliable and consistent coverage. Other methods, such as using a signal booster or Wi-Fi calling, may have limitations in terms of signal strength and coverage.
