7-Day Inactivity Causing “Not Registered” Status – Any Fix?

[ACL]

Hi Experts,


It's 2026 NOW!! Is anyone still experiencing the issue where extensions in 3CX become “Not Registered” after 7 days of inactivity?
For Android users, we understand that enabling the “Keep Active” option in the 3CX mobile app helps maintain registration, although it comes at the cost of higher battery consumption.

However, we are facing challenges with iOS users. Has anyone found a reliable solution or workaround for this?

Some suggestions mention using Background App Refresh, but this only works if the app remains in the background (i.e., not force-closed by swiping it away). In real-world usage, many users tend to close apps, which leads to the same issue recurring.

We would greatly appreciate if anyone could share:

• Any effective solutions or workarounds for iOS devices
• Best practices to prevent extensions from becoming “Not Registered” due to inactivity

Additionally, it would be ideal if 3CX could address or improve this 7-day inactivity behavior. We have a significant number of customers who rely solely on the 3CX mobile app for receiving calls, but their call volume is relatively low. As a result, they risk missing important calls when their status becomes “Not Registered” after inactivity.


Thank you in advance for your insights and suggestions.

Im guessing Vali's comments still applies then RE swiping closed?

Hello 3CX Forum Users,

We've found that after 7 days of no use on the 3CX app, the extension becomes unregistered and as a result cannot receive calls. This is the forum thread with answers but they might be out of date due to being posted in 2020: https://www.3cx.com/community/threa...nregisted-after-one-week-of-inactivity.70203/

I've already explained to the client that all the user needs to do is open the app and it'll register again, also raised the concern as to why the user hasn't at least opened the app once in the last 7 days. I've even explained that...

Yes, but we cannot customer not to swipe away the app from their background. So, is there any practical way for iOS users keep their status 'Active' after 7 days of inactivity?

Yes, open the app once a week.

There's no other way, period. And this will not change.

Note the app should also be opened after a phone reboot, such as an OS update.

I know people who like to close apps. iOS will manage this for you so it’s just unnecessary extra activity (battery usage) to reopen them. Since it’s an Apple limitation and 3CX has the 24h refresh to work around it, these folks are essentially shooting themselves in the foot by closing the app then wondering why it’s disconnected.

Wow, just wanted to chime in with a thank you for sharing note. I'm not an iOS guy and don't use any iOS devices. We've had a client complaining for months...years that the app doesn't reliably alert them of calls, especially the first call each day. We've done tons of troubleshooting, and I had no idea that swiping the app closed would disrupt registration and potentially keep it from getting PUSH notifications.
I'm now assuming that this may be a factor in the scenario and have advised them of such.

Is the 24h refresh supposed to stop the 7 days of inactivity or does that stop working after 7 days? The blog post you referenced isn't clear. Thanks!

I tried to test it this summer and it seemed to last past the 7 days. I've seen others post it's still an issue though. The thread linked above ends with a post saying it will do so as long as the app wasn't closed:

@AshleyG_LMS
iOS client does not have a "Keep Active" because it works exclusively by VoIP push.
Regarding the "Background App Refresh", this one instruct iOS to wake-up the app quietly every 24 hours so it can refresh push subscription. But app should be in the background - if was terminated by swipe up, that setting has no effect.
