Gotcha, I thought you were implying that you were going to be using the HD 58X with your interface.

I have no idea what the interface headphone output is for tbh
The audio output on an interface is best suited as either a slight upgrade over an onboard headphone output and/or for use with direct playback input monitoring.

If i understand correctly you are saying that, for my voice calls, neither the Solo or UMC22 is what I should buy?
You may want to consider the UMC202HD instead of the UMC22. As I understand it, you'll have better drivers and sample rates over the UMC22. The difference between the UMC202HD and Solo is minimal when strictly referring to audio input. Go with whatever is cheaper.
