Scenario is I have a CM where callers call into our agents. Basically, hits a VDN, does the TOD checks, agent availability checks etc.. If nobody is available/staffed in this call center it routes to another CM via IP trunks. Is there a step in the vector that can check that this other CM is reachable before the call is sent? And if it's not reachable, can direct to the next or another vector step within the originating CM?
