Is Having Multiple Phone Numbers Integrated Into the System Causing Frequent Phone Reset Issues?

Last updated on Jul 30, 2025

Overview

Some users report that having two or more phone numbers integrated with their Evo Voice softphone or device setup leads to frequent resets or instability. This article explores possible causes and provides steps to diagnose and resolve the issue.

Possible Causes

🔁 SIP Registration Conflict

  • If both numbers are registered to the same device or softphone app, SIP conflicts may occur.

  • This can cause the softphone to restart or deregister one of the numbers.

📱 Softphone Configuration Overload

  • Some devices or apps (e.g., Zoiper, Linphone, Evo Console) may not support concurrent dual registrations well.

  • Resource conflicts can trigger resets or cause the app to crash unexpectedly.

🔐 License or Session Limits

  • If your Evo Voice license or provisioning is limited to one number per device, the second line may cause service interruptions.

  • Re-authentication attempts can force resets.

⚠️ Network or VPN Issues

  • Split registration of multiple numbers over fluctuating networks or VPNs can cause missed keep-alive signals and reboots.

Troubleshooting Steps

  1. Check Device or Softphone Logs

    • Look for SIP deregistration events or app crash reports.

    • If using mobile softphones, confirm if the crashes align with incoming calls or switches between numbers.

  2. Review Your SIP Profile Configuration

    • Ensure that both numbers are not set to auto-register simultaneously on one device unless supported.

    • Use dedicated SIP profiles or split registrations across devices, if possible.

  3. Test with One Number Only

    • Temporarily remove one number and monitor if the reset frequency decreases.

  4. Check Network Stability

    • Perform ping or jitter tests, especially when switching between Wi-Fi and mobile data.

  5. Verify Licensing and Provisioning Limits

    • Contact Evo Support to confirm your account settings or whether your plan supports multi-number setup on the same device.

  6. Update or Reinstall Your Softphone

    • Ensure the latest version is installed.

    • Clear cached SIP credentials and reconfigure fresh.

Recommendations

  • Use Separate Devices for each number if dual SIP registration is unsupported on your current setup.

  • Avoid Simultaneous Auto-Registration of both numbers on a single device unless explicitly supported by Evo Voice or your softphone app.

  • Contact Support if resets continue despite following the steps above—we can check back-end SIP logs or provide provisioning options.
