we use JIRA IT-HELPESK as helpdesk tool for our customers.
We are a service provider in telecoms. For each client we create a service desk. For example for the customer "Red" we create a service desk "RED". for this service we add customers "one", "two", "three". My question is this: how to configure JIRA IT Helpesk for the customer "one", "two" and "three" can see all the tickets (one, two, three) at the web portal
