Call quality issues

Common causes:
  • Weak internet connection
  • Network congestion
  • Low bandwidth
  • Background apps using bandwidth
Solutions:
  1. Check your internet speed (minimum 1 Mbps stable upload/download required)
  2. Switch from WiFi to cellular data (or vice versa) to test stability
  3. Close other apps using heavy data (streaming, downloads)
  4. Move closer to your WiFi router
  5. Restart your phone to clear network cache
Test your connection: Visit speedtest.net to check your stability.
Common causes:
  • Unstable internet connection
  • Network switching (e.g., leaving WiFi range)
  • Low battery triggering “Power Saving” mode
  • Background app restrictions
Solutions:
  1. Try to stay on one network (WiFi or 4G/5G) during important calls
  2. Ensure phone battery is above 20%
  3. Disable “Low Power Mode” or “Battery Saver” (this often kills VoIP connections)
  4. Keep the Allo app open in the foreground
  5. Update Allo to the latest version
Common causes:
  • Using speakerphone (microphone picks up speaker output)
  • Volume too loud
  • Two devices in the same room on the same call
Solutions:
  1. Use headphones or earbuds (wired or Bluetooth)
  2. Lower the speaker volume
  3. Turn off speakerphone
  4. Ensure you aren’t logged in on multiple devices simultaneously in the same room
Check these items:
  • Microphone permissions are granted to Allo
  • Microphone is not physically blocked (finger, case, dust)
  • You are not on “Mute” inside the app
Solutions:
  1. iOS: Settings > Allo > Microphone (Toggle ON)
  2. Android: Settings > Apps > Allo > Permissions > Microphone (Allow)
  3. Remove your phone case temporarily to test
  4. Force close and restart the Allo app
Check these items:
  • Volume is turned up (Media volume, not just Ringtone volume)
  • App is not on Mute
  • Bluetooth is not connected to a different device (like car or earbuds in case)
Solutions:
  1. Press volume UP button during the call
  2. Toggle Speakerphone ON and OFF
  3. Turn off Bluetooth temporarily to ensure audio routes to phone earpiece

​
Connection problems

Check these items:
  • Internet connection is active
  • Allo subscription is active (Settings > Billing)
  • App is updated to latest version
  • “Airplane Mode” is OFF
Solutions:
  1. Toggle Airplane Mode ON for 10 seconds, then OFF to reset radios
  2. Log out of Allo and log back in
  3. Reinstall the Allo app
  4. Verify your subscription status in the web portal
Common causes:
  • Phone is on Silent or “Do Not Disturb” (DND)
  • Notification permissions are denied
  • Business Hours are set to “Closed”
  • “Gatekeeper” is blocking unknown numbers
Solutions:
  1. Check that Do Not Disturb is OFF
  2. iOS: Settings > Notifications > Allo > Allow Notifications (Critical Alerts if available)
  3. Android: Settings > Apps > Allo > Notifications (Enable all channels)
  4. Review your Business Hours in Settings > Call Handling
Common causes:
  • Carrier does not support “Call Forwarding”
  • Prepaid plans (often block forwarding)
  • Incorrect activation code or number format
Solutions:
  1. Retry the “Automatic Setup” in the Allo app
  2. Use the Manual Setup codes provided in the app
  3. Contact your mobile carrier to ask if “Call Forwarding” is enabled on your line
  4. Ensure you have enough credit (if on a prepaid plan)
Troubleshooting steps:
  1. Temporarily disable Gatekeeper (Call Screening) in Allo settings
  2. Ensure you have a strong cellular signal (forwarding is a carrier network feature)
  3. If Automatic setup fails, try Manual setup
  4. Contact Allo support if you receive a specific error code

​
App issues

Quick fixes:
  1. Force close the app (swipe up from bottom/home) and reopen
  2. Restart your phone
  3. Android: Clear App Cache (Settings > Apps > Allo > Storage > Clear Cache)
  4. Delete and Reinstall the app (your data is saved in the cloud)
Common causes:
  • Incorrect email format (e.g., space at the end)
  • Magic Link expired
  • Network firewall blocking login
Solutions:
  1. Double-check email spelling
  2. Request a new Magic Link (valid for 15 minutes)
  3. Check “Spam/Junk” folder for login email
  4. Try logging in via the Web App (on desktop) to verify account status
Check settings:
  1. System Settings: Ensure Allo has permission to show banners and play sounds
  2. Battery Optimization: Ensure Allo is set to “Unrestricted” or “No optimization” in battery settings (Android especially)
  3. In-App: Check Settings > Notifications to ensure they aren’t paused
Common causes:
  • Permissions denied
  • Sync interval delay
Solutions:
  1. iOS/Android: Go to Settings > Privacy > Contacts and ensure Allo is allowed
  2. In Allo, pull down on the contact list to refresh
  3. If using an Integration (HubSpot/Salesforce), check the Integration settings to ensure “Contact Sync” is enabled

​
Recording and transcript issues

Why this happens:
  • Call was made using the native phone app, not Allo
  • Call was a WhatsApp call
  • Call was extremely short (less than 3 seconds)
Verify: Only calls dialed inside the Allo app or received via Allo are recorded. Forwarded calls answered on your native dialer (without the app) may not record depending on configuration.
Common causes:
  • Processing delay (wait 2-5 minutes)
  • Audio quality was too poor for AI to process
  • Unsupported language (Allo supports 30+ languages, but needs clear audio)
Note: If the audio recording exists but transcript fails, you can usually request a “Retry” or just listen to the audio.
What affects accuracy:
  • Heavy background noise (wind, traffic)
  • Overlapping speech (people interrupting each other)
  • Low quality microphone
Solution: The summary is usually more accurate than the raw transcript. Use the AI Summary for quick insights.

​
Integration issues

Common causes:
  • Pop-up blocker prevented login window
  • Session timed out
  • Insufficient permissions on the CRM side (Admin required)
Solutions:
  1. Disable pop-up blockers
  2. Ensure you are an Admin on the CRM (HubSpot/Salesforce) account
  3. Clear browser cache/cookies and retry
Troubleshooting:
  1. Check if the Integration status is “Connected” in Allo Settings
  2. Verify the phone number exists in your CRM
  3. Disconnect and Reconnect the integration to refresh the token
  4. Wait 5 minutes (some CRMs have API rate limits)
Why: CRMs often struggle with different number formats (e.g., +33 6 vs 06).Solution: Allo attempts to standardize numbers to E.164 format (+1234567890). Ensure your CRM contacts also use the international format to prevent duplicates.
Check:
  • Integration is “Connected”
  • You haven’t deleted or renamed the connected Sheet columns
  • The Google Account connected has “Editor” access to the file
Fix: The most reliable fix is to Disconnect the integration and Reconnect it, selecting the spreadsheet again.
