Re: [Linphone-developers] Linphone logo customization

[Julien Favre-Bulle]

Dear Varun and all readers of this mailing list,

 

I would like to bring some clarification about the use of Linphone under a GPLv3 license.

 

When you decide to distribute a GPLv3 software, with or without alteration, modifications, extensions or integration with third parties, then you need to make available the entire source code of your product integrating this software to the customer or end users that receive this product.

To learn more about Linphone open source please review the license conditions provided in the following link to make sure you don't miss anything: https://www.gnu.org/licenses/gpl-3.0.en.html

 

You are allowed to re-skin Linphone but you have to distribute your re-skin app under GNU GPLv3 license (unless if you buy the proprietary license). This means that you must indicate that your app is released under GNU GPLv3 license into your app, for example in the setting part of the app and you have to make available the entire source code of your app for the end users (GITLAB or GITHUB is acceptable)

 

Distributing an app without a proprietary license or without respecting the GPLV3 conditions is constituting a copyright infringement.

 

Best regards,

 

Julien Favre-Bulle

Good afternoon, Varun!

I apologize for the delay in responding. We are very interested in customizing Linphone, including inserting the G4Flex logo and implementing other improvements. How can we help you carry out this customization? Would it be possible to provide your number on WhatsApp or Telegram to facilitate communication?

Our commercial team needs to obtain information about the costs and future steps needed to move forward with the project. We look forward to collaborating in this development.

Yours sincerely,

Hi Mardson,

 

As Linphone is open source with GPL licence. This means there is no restriction to use source code and customise the logo and other things.

 

I am doing such work for companies where I customise the Linphone with Customer logo and publish that to Google Play Store.

 

There are many other improvements included.

 

Please let me know if you are interested to work with me.

 

Thanks and regards

Dear sirs,

We would like to express our interest in customizing the Linphone Softphone with the inclusion of our company logo, G4Flex. We are eager to understand the procedures required for this customization, as well as the associated costs and the relevant contract that must be established to ensure a successful collaboration.

We thank you in advance for any attention and guidance you can provide us regarding this matter.

Yours sincerely,
