Doing a "Vlookup" in DAX

[brockshagena]

I am working with phone data and I am trying to determine if a missed call was returned or not.  The data looks like this.

ANI = Incoming Call # DNIS = Outgoing Call #

In this example you can see the agent missed two calls from the 253 number and then called that same number twice. I have tried duplicating the table, filtering it for outgoing and then creating a relationship ANI to DNIS.. that kinda works but not sure that is the approach seems to take a long time to load, basically doubling the size of the query.  Any advice would be much appreciated.

Thanks in advance.

I didn't see 253 number in your screenshot. Could you pls provide some sameple data (not the screenshot) and the expected output?
