If your Linkus Mobile app is not receiving push notifications for incoming calls. This can happen if: The app was force-closed (killed) before or during a PBX firmware upgrade. Push notifications are disabled either on the PBX extension settings or within the Linkus app itself. The device lacks network connectivity (Wi-Fi or cellular data) when the call arrives. Note: Even if your phone is outside the company network (on external internet), Linkus relies on Apple Push Notification service (APNs) to alert you of incoming calls. If push is blocked or fails, no ringing occurs—but the call is still logged as missed in the PBX. Verified Solutions: Option 1: Ensure Push Notifications Are Enabled on PBX Log in to your PBX admin portal. Go to Extensions > [Your Extension] > Linkus Settings. Confirm that "Accept Push Notifications" is enabled. If disabled, the PBX will not send push alerts to your device, and mobile.log will show: presence set client not allow push. Option 2: Check Linkus App Settings on Your iPhone Open the Linkus app. Go to Settings (gear icon) > Push Notifications. Make sure "Stop Push Notifications" is OFF. If enabled, the PBX logs will show: client set silent, not push. Option 3: Re-launch Linkus After PBX Upgrade If your PBX was recently upgraded to firmware version 83.22.0.134-beta1 or later (e.g., 83.22.0.138/139, 37.22.0.138/139, or 84.22.0.138/139), and you had previously force-quit the Linkus app, you must manually reopen Linkus once after the upgrade to re-establish push registration. Known Issue (Fixed in V23.3-GA): In versions prior to 83.22.0.138 (P-Series Software), if Linkus Mobile was killed before upgrading, push notifications would stop working until the app was relaunched. This is resolved in V23.3-GA, but affected users still need to open the app once post-upgrade. Option 4: Verify iOS System Permissions Go to iPhone Settings > Notifications > Linkus. Ensure Allow Notifications is ON and Sounds are enabled. Also check Settings > Linkus > Background App Refresh is enabled. Additional Recommendation: Ensure your PBX is running the latest V23.3-GA firmware (e.g., 83.22.0.139 for P-Series Software Edition), as it includes critical fixes for push notification reliability and security enhancements. Immediate upgrade is strongly recommended.
