Setting Up Sipnetic on Your iPhone

Configuring Sipnetic to work with your VoIP provider might seem a bit technical, but don't worry, we'll guide you through the process. Before you start, make sure you have the following information from your VoIP provider:

• SIP Username: This is your unique identifier for your VoIP account.

• SIP Server Address: The address of your VoIP provider's SIP server.
• Authorization Username (if required): Some providers require a separate username for authentication.
• Proxy Address (if required): The address of your VoIP provider's proxy server.

Once you have this information, follow these steps to set up Sipnetic:

1. Open Sipnetic: Launch the Sipnetic app on your iPhone.
2. Add a New Account: Tap the "+" button in the top right corner of the screen to add a new SIP account.
3. Enter Account Details: You'll be presented with several fields to fill in. Here's how to map the information you gathered from your VoIP provider to these fields:

Troubleshooting Common Issues

While Sipnetic is generally reliable, you might encounter some issues from time to time. Here are some common problems and how to troubleshoot them:

• Registration Failed: If Sipnetic fails to register with your VoIP provider, double-check your account details (username, password, server address) and make sure they are correct. Also, ensure that your internet connection is working properly. If you're using a firewall, make sure it's not blocking SIP traffic (ports 5060 and 5061).
• One-Way Audio: If you can hear the other party but they can't hear you, or vice versa, it could be a NAT (Network Address Translation) issue. Try enabling STUN (Session Traversal Utilities for NAT) in Sipnetic's advanced settings. You can use a public STUN server address like stun.l.google.com:19302. Also, ensure that your firewall is not blocking RTP (Real-time Transport Protocol) traffic.
• Poor Audio Quality: Poor audio quality can be caused by a number of factors, including a weak internet connection, a congested network, or an incompatible audio codec. Try switching to a different audio codec in Sipnetic's settings (e.g., G.711). Also, make sure that your microphone and speaker are working properly.
• Push Notifications Not Working: If you're not receiving push notifications for incoming calls, make sure that notifications are enabled for Sipnetic in your iPhone's settings. Also, ensure that Sipnetic is allowed to run in the background. Some battery-saving modes can prevent push notifications from working properly.
• App Crashing: If Sipnetic is crashing frequently, try restarting your iPhone. If the problem persists, try reinstalling the app. Make sure you're using the latest version of Sipnetic.

If you're still experiencing issues after trying these troubleshooting steps, consult Sipnetic's documentation or contact your VoIP provider for assistance.
