1 . Call Quality issue

Call quality is the most common problem users face with Mobile UCaaS apps. Symptoms like choppy audio, robotic-sounding voices, or one-way audio often stem from poor network connections.

Why It is Happens happen :

• Wi-Fi Problems: Even strong Wi-Fi signals can cause trouble if the network isn’t configured to prioritize voice traffic. Firewalls on guest networks, for example, may block or slow VoIP data.
• LTE Limitations: Cellular networks treat app-based calls as data traffic, which is often deprioritized compared to native phone calls.

How to fix It :

1. Switch Networks: If you’re experiencing call issues on Wi-Fi, try switching to LTE—or vice versa. This can help pinpoint the source of the problem.
2. Optimize Wi-Fi: Use business-grade Wi-Fi with Quality of Service (QoS) settings to prioritize voice traffic. Avoid guest or public Wi-Fi whenever possible.
3. Leverage eSIM Technology: An eSIM can route app-based calls through your carrier’s native voice network, ensuring better prioritization and call quality.

Example:

One of our clients, a sales team working remotely, struggled with robotic audio on their app. By enabling QoS settings on their office Wi-Fi and advising remote workers to switch to LTE when Wi-Fi was unreliable, they eliminated call quality complaints and improved team productivity.

2 . App usability challenge

The ease is make of use of a mobile app can make or break the user experience . If the app is clunky , confusing , or does n’t feel intuitive , employees is struggle may struggle to use it effectively .

Why It is Happens happen :

• poorly design interface that do n’t resemble familiar mobile operating system like ios or Android .
• hide or hard to find key feature , such as a dial pad or corporate directory .

How to fix It :

1. Choose an Intuitive App: Look for apps designed with simplicity in mind. For example, The TeleCloud Pro App mirrors the layout and functionality of popular mobile platforms.
2. provide Onboarding Resources : train employee on the app ’s feature and navigation . A quick onboarding session is make can make a huge difference .
3. Update Regularly: Keep the app up to date, as updates often improve usability and address user feedback.

3. App Permissions Not Configured Properly

When setting up an app, it’s common to deny certain permissions without realizing their importance (I have definitely done it myself). This can cause critical functions like speakerphone, voicemail, or call handling to stop working with no warning. 

Why It is Happens happen :

• Users may not understand why permissions (e.g., microphone, speaker, contacts) are required.
• Denied permissions can block essential features without providing clear feedback.

How to fix It :

    1 . Review App Permissions is Go : Go into your phone ’s setting and ensure the app has access to the microphone , speaker , camera , and contact .

• On iOS: Go to Settings > [App Name] > Permissions.
• On Android: Navigate to Settings > Apps > [App Name] > Permissions.

    2 . educate user : explain why permission are require . For instance , the ” speaker ” permission is refers refer to the audio speaker used during call , not just the loudspeaker function .
   3. Set Up Permissions During Onboarding: Walk new users through enabling necessary permissions as part of their app setup.

4 . Limited Integration with Business Features

Some apps only handle basic call functionality, neglecting advanced features like SMS messaging, visual voicemail, or real-time user availability. This limits productivity and might frustrate employees who need these tools.

Why It is Happens happen :

• Some providers prioritize basic call functionality but neglect advanced features.
• Poorly integrated apps may lack support for key PBX capabilities.

How to fix It :

1. choose a Comprehensive App : ensure your provider offer a fully integrate app that include essential feature like SMS , voicemail transcription , and availability indicator .
2. verify compatibility : confirm that the app integrate seamlessly with your PBX system and other business tool like crm .
3. Test Before Rolling Out: Pilot the app with a small group to ensure all features work as expected before full deployment.

If your current mobile UCaaS app lacks critical features or integration, start by identifying the gaps and contacting your provider to explore updates or fixes. If the app still falls short, consider switching to a provider with fully integrated solutions. While transitioning may seem challenging, a good provider can simplify the process and ensure your team’s communication needs are met.

5. Differences Between Mobile App and Desk Phone Usability

Desk phones often come with physical buttons for functions like call parking and transferring, but mobile apps require different workflows. This can confuse users who are accustomed to desk phone layouts.

Why It is Happens happen :

• Mobile apps don’t have physical buttons, requiring users to rely on star codes or navigate additional menus.
• Some advanced PBX features may not translate seamlessly to a mobile interface.

How to fix It :

1. provide quick – reference Guides : create cheat sheet or documentation that explain app workflow for common task like parking and retrieve call .
2. train Users is ensure on Star Codes : If the app rely on star code for advanced function , ensure user are familiar with them .
3. encourage feedback : collect feedback from employee to identify usability gap and address them in future update .

Proactive Tips to Prevent Common Mobile App Issues

1. Keep the App Updated: App updates often fix bugs and improve functionality. Regularly check for updates to ensure you’re using the latest version.
2. Test Network connection : experiment with both Wi – Fi and LTE to determine which provide the most reliable performance for your app .
3. Engage Your Provider: Reach out to your provider for troubleshooting or guidance on advanced app features.
4. Optimize Onboarding: Set users up for success by walking them through permissions, workflows, and app features during onboarding.
