7 Landline Transcription Tools: Record & Transcribe Calls
June 8, 2025


When using a landline for business, a common challenge is that it's difficult to record or share call content.
- I want to share landline call content.
- Taking notes is a hassle.
- I want to record call center interactions.
By transcribing landline call content using AI, you can solve these problems and streamline your operations!
However, recording and transcribing with a regular phone is difficult, so you'll need to use a "cloud PBX" or connect a recording device.
This article thoroughly explains the benefits, methods, and recommended services for transcribing landline calls!
3 Benefits of Transcribing Landline Calls
First, let's look at the benefits of recording and transcribing landline calls!
1. Store Call Content as Data
When you transcribe landline calls, you can save the content as text.
Taking notes on phone calls received at the office can be very tedious.
If the call is long, it becomes even harder to write down everything.
By automatically transcribing landline calls, you can record everything said on the landline in text.
All call center interactions can also be saved using a transcription tool.
2. Accurately Share Call Content
Accurately understanding and sharing call content is another benefit of transcribing landline calls.
When taking notes while listening to a call, it's easy to miss information or write down something incorrectly.
In contrast, transcribing with AI allows you to record everything accurately.
You can perfectly grasp important details, from meeting schedule changes and product inquiries to complaint handling.
Since it's text data, it's easier to share compared to audio files.
You can instantly share it internally via email or chat apps.
3. Easy Management of Call Interactions
Landline transcription also helps streamline business management.
Inquiries to the workplace or conversations at a call center significantly impact the company's external image.
If inappropriate responses occur, it can damage the company's reputation.
By transcribing and recording landline content, you can check call content and visualize interaction quality.
It also allows you to accumulate examples of phone interactions, which is useful for new employee training and handovers.
How to Transcribe Landline Calls
To transcribe landline calls, you need to record them.
Here's how to record and transcribe landline call content.
1. Use a Cloud PBX Service
A recommended way to record landline calls is to use "Cloud PBX."
Cloud PBX is a system that manages phone calls over the internet (in the cloud).
With Cloud PBX, you can receive calls over the internet and forward them to your computer or smartphone to talk.
Just like forwarding an external company landline call to an internal extension, one
It's also possible to share and use the same phone number across different computers and smartphones.
Call Content Can Be Stored in the Cloud
With cloud PBX, calls go through an internet server.
Many cloud PBX services offer an option to record and store call content on the server.
By downloading the audio files from the cloud and transcribing them with an AI transcription service, you can easily convert call content into text.
2. Using a Landline Phone with a Recording Function
Some landline phones come with a recording function.
The key point when choosing a phone with a recording function is whether you can not only listen to the recorded audio but also extract it as an audio file.
Office phones (business phones) allow you to save audio to a USB drive or SD card, making it easy to copy to a computer and transcribe with an AI transcription service.
Be aware that many home landline phones only allow you to listen to recorded audio and cannot save it as an audio file.
3. Using a Recording Device Connected to a Landline Phone
Recording devices that connect to landline phones are also commercially available.
Installation is simple.
Remove the handset cord from your landline phone and attach the recording device in its place.
Then, connect the handset to the recording device, and installation is complete.
Calls are automatically recorded every time they come in, so you can copy the saved audio to your computer and transcribe it.
The key here is to purchase an office-grade recording device.
Home recording devices sold as scam prevention tools often cannot save audio files, or if they can, the recording time is very short, so be careful.
