So, I want to make sure I'm doing this right.. I'm building a "mega ingest" that will cover multiple systems and sites (specifically OH MARCS, WV SIRN, and AEP) and I'm planning on sending it to Calls. I put in a couple applications for Calls nodes for Wayne Co to start out.. but I wanted to make sure I'm covering things right. Do I need a separate Calls node for each site or can I send multiple sites to one node, or what is the best way to go about it?
