This article provides a detailed, step-by-step guide to successfully setup Linphone with Google Voice and fax app for all your communication needs.

What Is Linphone?

Linphone is an open-source Voice over IP (VoIP) application that uses the SIP (Session Initiation Protocol) for audio and video calls. It’s a powerful tool for making calls over the internet, supporting features like HD voice quality, encryption, and video conferencing. Linphone is available for various platforms, including Windows, macOS, Linux, Android, and iOS.

Step 2: Set Up Google Voice

Google Voice provides a unique phone number that you can use for calls, texts, and voicemail. Since Linphone relies on SIP and Google Voice does not natively support SIP, a third-party service like Callcentric acts as a bridge.

2.1 Create a Google Voice Account

1. Go to Google Voice.
2. Sign in with your Google account.
3. Choose a Google Voice number and complete the setup.

2.2 Link Google Voice to a SIP Provider

Since Linphone operates on SIP, you’ll need a SIP provider to connect Google Voice. Callcentric is a popular choice.

1. Sign Up for Callcentric:
   • Visit Callcentric.
   • Create an account and verify your email.
2. Obtain a SIP Account:
   • Log in to Callcentric and navigate to your dashboard.
   • Note down your SIP credentials: username, password, and SIP server.
3. Link Google Voice to Callcentric:
   • In Google Voice settings, forward calls to your Callcentric number.
   • Enable call handling in Callcentric to route calls to your SIP account.

Step 3: Configure Linphone with SIP Credentials

Once your Google Voice is linked to a SIP provider, configure Linphone to use these credentials.

3.1 Add a SIP Account to Linphone

1. Open Linphone and navigate to Settings or Preferences.
2. Go to the Accounts section and select Add Account.
3. Enter the following details:
   • Username: Your Callcentric SIP username.
   • Password: Your SIP password.
   • SIP Server: The SIP address provided by Callcentric (e.g., callcentric.com).

3.2 Test Your Google Voice Connection

1. Make a test call from Linphone using your Google Voice number.
2. Ensure both incoming and outgoing calls are working as expected.

Step 4: Set Up a Fax App with Linphone

To send and receive faxes, you need a fax app compatible with SIP protocols. Many apps, like eFax and MyFax, support digital faxing over VoIP.

4.1 Choose a Fax App

Popular fax apps include:

• eFax: Offers T.38 faxing for SIP accounts.
• MyFax: Simple and user-friendly interface.
• HelloFax: Integrates with email and cloud storage services.

4.2 Configure the Fax App

1. Sign up for your preferred fax app.
2. In the fax app’s settings, enter your Linphone SIP account details:
   • SIP username.
   • SIP password.
   • SIP server address.
3. Test sending and receiving a fax to ensure functionality.

4.3 Enable T.38 Protocol (If Supported)

If your fax app supports the T.38 fax protocol, enable it for better compatibility and reliability during fax transmissions.

Step 5: Optimize Your Setup

To ensure a seamless experience, optimize your setup by addressing potential issues and enhancing functionality.

5.1 Network Configuration

1. Use a stable internet connection with sufficient bandwidth.
2. Configure your router to prioritize SIP traffic for Linphone and your fax app.
3. Enable port forwarding for SIP and RTP ports used by Linphone.
