Yes this is possible, for instance if you have one phone in the office and one phone at home. 

However you cannot share extensions for the same line (at the same time) so you will need to switch off the phone that you are not using so that you can receive incoming calls to the phone that you wish to use in a different location. 

Please do not put the phone you are not using on 'DND' as this will affect the phone you are using - you will need to switch off the phone you are not using so that the phone you are using works correctly for incoming calls and for click2call to work.
