Leads Module with commercials and telemarketing companies

Leads Module with commercials and telemarketing companies

Good morning,

I have a problem. I have two telemarketing companies and my own commercials that draw on the records we have in the leads module. I would like to know if there is any option so that each one can only see his records as owner and not see those of other people (commercial or telemarketing)
Thanks for your comments,

Regards
