No longer getting calls on my cell phone

[cwhc]

Even if my cell phone is the only device that I am signed into, and the application is up and running and active on the screen when I call my number Jabber does not ring or even show that there is an incoming call.  When I called our help desk that says that's the way it works on iPhone now, but I have an android phone. Outgoing calls still work fine it's just incoming calls. Did Cisco do something to stop this function from working?

We are a webex calling site with no local call manger and this is happening to us as well.  The app will work for a little while and on some iPhone without issue but after a while it no longer rings through.  My iphone for example working without an issue.  But I have another that i have had to reinstall the app many times. both on ios 15.5

I am grateful to the responses mine was simple. I turned on DND "do not disturb", but then turned it off my two computers and Cell phone saw the change but in the self service port **bleep** was sill set to DND

It sounds as if your IT department has not done the necessary upgrades and/or configuration for push notifications.  This guide explains and provides instructions. Without this, you simply do not get notified when a call is delivered to mobile devices.  Basically, Apple let the way here with new requirements in iOS version 13, if I recall correctly.  Apps needed to be updates to accommodate new methods, as did the underlying infrastructure.
