Linking records from different modules

Linking records from different modules

Hello, 
Is there a way to link customer call records from the 'Calls' module to specific account and contact records? I've realized that our customer meeting reports are linked to both the contact and the Account records, in related list fields but the calls only show in the calls module - without linking to the corresponding Account and contact records. We've only just started logging all customer calls in Zoho CRM... 
Thanks!
