Can you this with an desk phone via the headset jack?

The EPOS Sennheiser SP 20 isn't marketed to be used with a standard desk-phone. The exception to the rule is that many newer desk phones do in fact have USB ports which support audio in which case this would be a perfect way to expand the speakerphone capabilities on a budget. https://www.amazon.com/Sennheiser-506049-Sound-Enhanced-User-Friendly-Connection/dp/B00K2RQ94C/ref=sr_1_1?keywords=SP+20&m=A1PBDPFFCAVYZF&qid=1651600229&s=merchant-items&sr=1-1

What is the difference between this model ml and the regular sennheise sp20 usb?

The SP 20 is designed only to be used with PC's, smartphone, and tablets. The SP 20ML is designed to be used with Skype for Business, PC's, smartphones, and tablets. I have the SP20 ML and love it. I use it everyday for both personal and business.
