Cisco SPA 525G randomly refreshes phone

[globalcomm]

We had this problem with two of our customers. Only with the Cisco 525g2 and all the 500 series of phones. Apparently you need to make sure there are no voice mail messages in the 3cx. We set the setting to email a copy of the VM and the remove from the 3cx. If there is even one VM in the users 3cx VM the phone will continue to refresh. This issue needs to be fixed by 3cx. Until this is done I would not buy or recommend ANY Cisco 500 series phones. Use the Yealink's

Can anybody confirm a working resolution for this issue?
I'm using spa525G2 phones with 3cx V11SP4 in multi tenant config.
