Does OS Ticket have the ability to integrate with some kind of chat platform that can be used along with the tickets created in OS?
natively no. But it's open source so you can implement this in many different ways.
One way a few years back was this: https://forum.osticket.com/d/89826-live-chat/3 https://github.com/LiveHelperChat/osTicket
I can't get it working... i think it's too old for the version that is out now. Is there some other way?
