Sangoma Talk Softphone – Known Limitations & Best Practices

This article explains the known limitations of Sangoma Talk and provides best practices to help ensure reliable call quality and performance.

Known Limitations

Does Sangoma Talk work the same as a desk phone?

Not always. Sangoma Talk relies entirely on your internet connection, while desk phones typically use a wired network. Because of this, call quality and reliability may vary compared to a physical desk phone.

Can call quality be affected?

Yes. Call quality can be impacted by:

  • Weak or unstable Wi-Fi or cellular connections

  • Network congestion

  • Public or shared Wi-Fi (hotels, airports, cafés)

  • High latency or packet loss

These conditions may cause audio delays, echo, dropped calls, or one-way audio.

Does Sangoma Talk work on all networks?

No. Some networks restrict or block VoIP traffic, including:

  • Corporate or guest Wi-Fi networks

  • Hotel or conference Wi-Fi

  • International cellular providers

If VoIP traffic is blocked, the app may not register or may experience audio issues.

Is Sangoma Talk reliable while traveling internationally?

Not guaranteed. International roaming, foreign carriers, and local firewall policies can cause registration failures, call delays, or poor audio quality. At times, you may need to provide your IPv4 for whitelisting while traveling.

Are push notifications always reliable?

Push notifications depend on your device and network. Delays or missed calls may occur if:

  • Battery optimization or power-saving modes are enabled

  • The app is restricted from running in the background

  • The device has a weak or unstable data connection

Can I receive calls if the app is closed?

  • Mobile: Calls rely on push notifications within your device settings, which may be delayed if background activity is restricted.

  • Desktop: The app must be open and running to receive calls.

Can using multiple devices cause issues?

Using Sangoma Talk on multiple devices may result in:

  • Calls ringing on several devices at once

  • Missed calls if one device loses connectivity

  • Delays when switching between devices

This behavior is expected and system-dependent.

Does Sangoma Talk work during internet outages?

No. If your internet connection is unavailable or unstable, Sangoma Talk will not function.

Are all operating systems supported?

Sangoma Talk supports current and recent operating systems. Older or unsupported versions may experience limited functionality or may not work at all.

Best Practices for Reliable Use

Use a Stable Internet Connection

  • Use a strong Wi-Fi connection or a wired Ethernet connection (for desktop users).

  • Avoid public Wi-Fi when taking important calls.

Prefer Wi-Fi Over Cellular

  • Cellular networks can introduce latency and packet loss.

  • If using mobile data, ensure a strong LTE or 5G signal strength.

Keep the App and Device Updated

  • Install the latest version of Sangoma Talk.

  • Keep your device’s operating system up to date.

Allow Notifications and Background Activity

For mobile users:

  • Enable push notifications.

  • Disable aggressive battery-saving or background restrictions for the app.

Use a Quality Headset

  • Use a USB or Bluetooth headset instead of built-in speakers and microphones.

  • This helps reduce echo and background noise.

Keep the App Running

  • Desktop users should keep the app open during work hours.

  • Mobile users should avoid force-closing the app.

Avoid Switching Networks During Calls

  • Switching between Wi-Fi and cellular during a call may cause drops or audio issues.

Test Networks When Traveling

  • International and hotel networks may restrict VoIP.

  • Test the app before relying on it for business-critical calls.

Restart When Issues Occur

  • Restart the app or device if you experience audio or connectivity problems.

Know When to Use a Desk Phone

  • For emergency calls, high-volume calling, or critical conversations, a physical desk phone may provide more consistent reliability.

Contact Support if Problems Persist

If issues continue, contact a SoundCurve support agent and provide:

  • Device type

  • Network type (Wi-Fi, cellular, office)

  • Location (especially if traveling) IPv4

  • Time and description of the issue
