Hello. I have a Cisco desk phone, mobile app and desktop app with RingCentral. The mobile and desktop work perfectly. However, whenever I get a call my Cisco desk phone it does not ring or show that there is an incoming call. It is not an issue with the volume because it does not even register the call or show on the screen that I have an incoming call. I can make calls out from the Cisco phone, so I know that the phone connection works it just does not alert me for incoming calls. I pick it up to try to answer on my Cisco but it is silent. I have to answer only on app or desktop.

Please advise.

Thanks in advance
