Recording Access

My question is about calls recording access.
Recording is enable on all extensions and Admin can access all.
I would like to give access one supervisor to listen calls only his group extension’s.
I can’t figure out how to do this.
Any help would be appreciated.

A possible method would be to give them access to the CDR table. It has the calls recorded in the view. We buy the $25 module for FreePBX and it works pretty good.

Thanks for reply dickson.
Any free solution available for this ?
