Linphone SIP Account Authentication Fails: Continuously Prompted to Verify Password, Unable to Make Calls

Linphone SIP Account Authentication Fails: Continuously Prompted to Verify Password, Unable to Make Calls

This article will discuss the common issues faced while setting up a Linphone softphone using a SIP account created online. Specifically, we will cover two main problems: the authentication issue and the inability to make calls. By understanding these concepts and implementing the suggested solutions, you can successfully configure your Linphone software phone and start making calls.

1. Authentication Issue

After adding a SIP account to Linphone, you may encounter an authentication issue where the software continuously prompts you to verify your password. This problem can occur due to several reasons, such as incorrect password input, server-side problems, or improper account setup.

1.1. Incorrect Password Input

Make sure you have entered the correct password for your SIP account. Double-check for any typos or mistakes in character case. If you have forgotten your password, you can usually reset it through the online platform where you created the account.

1.2. Server-side Problems

If the server is experiencing issues, it may not be able to authenticate your SIP account properly. In this case, you can try the following steps:

• Check the server status on the provider's website or social media platforms.
• Contact the SIP account provider's support team for assistance.
• Wait for some time and try again later if the server issue is temporary.

1.3. Improper Account Setup

Ensure you have correctly set up your SIP account. Here are some steps to follow:

1. Check the account's domain, username, and password. They should match the details provided by your SIP account provider.
2. Verify that the transport protocol (UDP, TCP, or TLS) is correctly configured.
3. Confirm that the registrar server address and port number are correct.
4. Make sure that the outbound proxy and STUN/TURN server settings are accurate.

2. Inability to Make Calls

After successfully authenticating your SIP account, you may still face issues making calls. This problem might be due to a lack of proper network configuration or incorrect codec settings.

2.1. Network Configuration

Ensure your network is properly configured for SIP communication:

• Check your firewall settings to allow SIP traffic. This usually means allowing traffic through specific ports (5060 for SIP, and 10000-20000 for RTP).
• Make sure your router supports SIP communication and is not blocking any necessary ports or protocols.
• Use a stable and high-speed internet connection to avoid call quality issues.

2.2. Codec Settings

Codec settings might also impact your ability to make calls. Here are some steps to follow:

1. Check the codecs supported by both your Linphone software and your SIP account provider.
2. Ensure the codecs are correctly configured in your Linphone settings. Typically, you should prioritize Opus and G.722 for better call quality.
3. Verify that the preferred codecs match between your Linphone and your SIP account provider.

In this article, we have discussed common issues while setting up a Linphone softphone using a SIP account created online, specifically the authentication issue and the inability to make calls. By following the suggested steps and checking the relevant configurations, you can successfully set up and use your Linphone software phone.
