When calls disconnect unexpectedly or cut off during a conversation, it can disrupt your business and frustrate your callers. This usually points to a network issue, device problem, or occasionally a configuration setting. Go through the points below in order.

The most common cause of dropped calls is an unstable or fluctuating internet connection. If your connection drops even briefly, the call will disconnect immediately.

How to check: run a speed test at fast.com or speedtest.net. If your upload speed is below 1 Mbps or varies significantly, this is likely the cause. Look for any pattern — does the problem happen at certain times of day? On certain devices?

How to fix: if you are on WiFi, try switching to a wired connection (Ethernet cable) if possible — this is more stable. If you must use WiFi, move closer to the router. Contact your internet provider if drops continue — they may need to check your line stability.

Sometimes the issue is not your internet connection itself, but your router or modem. A router that is overheating, running outdated firmware, or struggling with too many devices can cause intermittent disconnections.

How to check: check your router's temperature — it should not be hot to the touch. Look for any warning lights on your modem or router. Check your router's admin panel to see if firmware updates are available.

How to fix: restart your router and modem by unplugging them for 30 seconds, then plugging them back in. Ensure your router has proper ventilation. Update the firmware if available. If the problem continues, check with your internet provider — you may need a hardware replacement.

If someone else on your network is downloading large files, streaming video in high quality, or running backups, they consume bandwidth and can cause your call to drop.

How to check: check whether any other devices on your network are using the internet heavily. This is especially common in offices where multiple people share one WiFi network.

How to fix: ask other users to pause non-critical activities during important calls. Consider using a wired connection for your device, or asking your team to prioritize Romulus traffic on your router settings (some routers allow QoS — Quality of Service — configuration).

If your phone or computer is running too many apps or has low storage, it can cause the Romulus app to disconnect or crash during a call.

How to check: close unnecessary apps on your device. Check your device's storage — if you have less than 10% free space, this can cause problems. Check whether your device is overheating.

How to fix: close unnecessary applications before making important calls. Clear your browser cache and temporary files. Restart your device to free up memory. Consider freeing up storage space by moving files to cloud storage or deleting unused apps.

Sometimes the Romulus app's cache (stored data from previous sessions) can become corrupted, causing disconnections or crashes.

How to check: if drops started suddenly after an update, or if restarting the app temporarily fixes the problem, a corrupted cache is likely the cause.

How to fix: clear the app cache. On Windows: go to Settings → Apps → Romulus → select "Clear cache" (or uninstall and reinstall). On Mac: open Finder → Library → Caches → delete the Romulus cache folder → restart the app. On iOS: go to Settings → General → iPhone Storage → Romulus → select "Offload App", then reinstall. On Android: go to Settings → Apps → Romulus → Storage → Clear Cache.

If you are using mobile data (3G, 4G, 5G), poor coverage or signal drops can cause calls to disconnect.

How to check: if you only experience dropped calls when on mobile data, this is the cause. Check your signal bars — if they are weak or fluctuating, your coverage is unreliable.

How to fix: use WiFi whenever possible. If you must use mobile data, try a different location with better coverage. Switch to a different mobile carrier if coverage is consistently poor in your area.
