Alcatel Unleashed

does Alcatel support simultaneous ringing on analog extension and mobile number. I have configured on digital extension but want this feature on analog extension. need help.

I think this is possible - you need to manage "The OmniPCX Integrated Cellular Client service is also referred to as a Remote extension".
Mobile set - managed like Remote extension. After you can use or hunt group with analog set+Remote extension or (for Remote extension in multi-line mode) set supervision (route call to analog set and supervision on Remote extension).
