Here’s whether cell phone lines can get crossed:
Yes, cell phone lines can get crossed even in the modern era. With modern, digital lines, you will not randomly hear different conversations while you maintain one connection.
Instead, you can get randomly connected to the wrong person entirely, leading to a single wrong conversation instead of a mix of conversations.
If you want to learn all about how cell phone lines can get crossed, then you’re in the right place.
Let’s jump right in!
How Do Cell Phone Lines Get Crossed?
How does a conversation get from one phone line to another? The answer to that depends on the type of communication being used.
Phones can run on analog or digital lines, and these forms of communication are so different that the explanations don’t have much crossover.
It’s easiest to understand this situation by comparing old analog phone systems to new digital systems. The analog systems include landline phones and the switchboards that have been in use for over a hundred years.
With this technology, conversations are sent as waves along the phone lines. If phone lines aren’t properly shielded, they can pick up signals from each other. That leads to what is known as crosstalk. You can randomly hear conversations of people you didn’t call.
With cell phones, crosstalk can still happen, but it’s a little different. In this case, the analog systems use radio waves to communicate. If two connections on the same cell tower have signals that are close enough, you can pick up part of the wrong signal and get the same kind of crosstalk.
It’s important to understand that cell towers no longer use analog communication, and digital systems are fundamentally different. With a digital phone call, information is sent in packets.
Crosstalk can happen, but it happens with individual packets, so you can’t get a whole conversation from someone else. Instead, you’re more likely to get random garbled sounds.
Despite the fact that digital systems operate on different fundamentals, you can still hear weird conversations or connect to the wrong person. You can even receive the wrong text message. What’s going on?
It has to do with signal matching and pairing. Digital communication uses encryption and a lot of signal processing techniques to ensure that conversations are properly matched and can’t be overheard. By and large, it’s successful, especially when it comes to overhearing conversations via crosstalk.
You won’t get the random bleed over of conversations like you may have experienced with analog systems. Instead, what can happen is that the programs controlling the matchmaking between devices can mess up.
This is often referred to as a digital handshake. It is where two devices match codes to ensure that they are talking to the right device. If a handshake program has a bug in it, you can get paired with the wrong person.
Keep in mind that this will reroute the entire line. You’ll connect to the wrong person entirely. It will not be a similar experience to when you hear talking while the phone is ringing on an older system. That is fundamentally different.
There are other things that can cause you to connect to an unintended person that have nothing to do with crossed lines. The easiest example to understand is a line change.
Let’s say you are trying to call an old friend. You dial the number, and a complete stranger answers the phone. You double-check. You called the right number, but that number doesn’t belong to your friend anymore.
It’s usually because they changed their phone account and got a new number. This is the most obvious example, but there are plenty of other situations that can cause a line change. Before you can be sure that a missed connection is because of crosstalk or digital communication flaws, it always helps to ensure that you have the right number for the person you are trying to reach.
Even if you do have the right number, features like call forwarding (more on this later) can reroute your call and ultimately connect you to the wrong person.
What Can You Do About Cell Phone Lines Getting Crossed?
Knowing that phone lines sometimes cross doesn’t really help resolve the real problem. If you’re connected to the wrong person, your communication fails.
You need ways to overcome this challenge. There are a few things you can do, and they depend on the ultimate reason why you aren’t connecting to the right person.
Contact Your Carrier
If you are having handshake issues and connecting to the wrong number, only your carrier can resolve this issue. Contact them.
They will likely run through some troubleshooting steps to determine where the call is occurring. They’ll cover most of the other things listed throughout this explanation.
If they do find that the digital handshake is the source of the problem, all of the fixing will happen on their end. Those are system-level problems and likely have nothing to do with your phone in particular.
Double Check Numbers
Most of the time, though, the problem will not be linked to a digital handshake or other carrier issues. In the majority of cases, people connect to the wrong number because of a user error or misbehaving feature.
Let’s start with the former. It’s easy to dial a wrong number, even with a smartphone, when contacts aren’t clear. You might have multiple contacts with the name.
Even more common is having multiple phone numbers for one contact. It’s easy to pick the wrong person, and then you won’t connect properly, especially if one of those numbers is old and no longer belongs to the person you are trying to reach.
Before assuming that there are signals being crossed, always double-check phone numbers.
Call forwarding is a feature that makes it easier to manage multiple phone numbers. If you have a dedicated work line, you might forward calls from there to your home phone for a work from home day (or any countless number of other reasons).
When you set this up, people dial the work number but are ultimately connected to your personal phone. Call forwarding is the mechanism that makes this work.
That means there’s a chance that call forwarding can be a problem. If it isn’t set up correctly, it can cause you to connect with complete strangers. One common way this happens is deep in the settings.
Call forwarding is set up on most smartphones to redirect people to your voicemail if you don’t answer. But, an additional setting can redirect to another number if you are unavailable (such as the phone being off or out of service).
With this, someone could call you, hit the uncommon call forwarding settings, and then be forwarded to a different phone number. If that phone number is incorrect, they’ll get a complete stranger.
It’s a specific example, but it paints a picture. Every feature has the potential to complicate things, and call forwarding, in particular, can cause people to connect to the wrong line.
