To get better Support for customer we work together with another Company which use OTRS.
Currently, if we do not have the knowledge We fill out a ticket inside the ticketsystem from the other company, gave them our customer data and the contact our customer.
It would be nice If there is a Solution that we could somehow use Zammad as Proxy for OTRS or other zammad Installation. The best solution would be that the customer do have to change the ticketsystem to a third company. (Kind of federated ticketsystem)
May there is a need for a protocol (like ActivityPub) for this?
