I have found that from time to time phones connected to IPecs cloud systems will fail to connect. They sit there at a screen saying No Ack and giving you a range of options.
Usually forcing global provisioning again gets them working.
On the screen it boots to press * for the [SET] option
It asks for a password – enter 147*
Select Option3 – Default
It asks, Default all profiles, are you sure?
Select YES
Press the BACK button
Reboot Now = YES
Shortly into the reboot the words “Global Provisioning” will display . Hit the Yes button
Hopefully this will help get someone back up and running.
