TheWeave,
Have you been able to recreate the scenario that the manager is complaining about?
I am not sure why you would need a CRA going to a CRA that just has a timeout to a HG, unless it is playing a message prior to the transfer. Regardless the system forwarding, and Dynamic Extension, of a phone in a Hunt Group isn't followed, but the manual forwarding of a phone in a Hunt Group is.
So, the one way for the call to get out to a users cell phone is for one of the members to be manually forwarded out to that cell phone.
The only other way for a call to leave the Hunt Group is via the Announcement, Overflow and Recall destinations. The Announcement and Overflow keep the caller in queue within the Hunt Group while they "conference" the caller to another source; typically a RAD or CRA. The Recall destination will transfer the caller out to another location which effectively removes the caller from the queue to be answered.
Thanks,
TE
