If you are using CUCM 12.0+ it may be due to the MRA Access Policy:

The far more likely scenario is that your Expressway deployment, or the firewall/NAT configuration surrounding it are not configured properly.

Can you look at your expressway-E for logs associated with your phones public IP.....

Last time I had one of these questions it was that the device was not build or associated with users correctly.

Do you see any error messages on the logs?

Hi Emad,

Please try to reset jabber in mobile once and if you still have issue then share Jabber problem report from mobile here to check the issue.
