Calls that are distributed via a line group ignore all call forward settings from the line group members, the Use Forward Settings of Line Group Member setting only works if it's used in a call flow which a user sends the call to the hunt pilot, that setting is checked in the hunt pilot for a CF option, and the original call forwarder has the CF no coverage option.
You have two options:
A) choose a single phone to which forward calls after no answer or busy, that may be a cell phone or anything else you like
B) configure SNR for the line group members to their mobile rings along with the company number, and then adjust the SNR timers to either let the individual's VM answer, or prevent that from happening by ending the call before the VM answers and the line group logic follows its course.
