look up any word, like yeet:

2.
to telecommute using VOIP or voice over IP (such as Avaya or Vonage) so that the telecommuter appears to either be in the office or other nearby location because the VOIP service provides a local caller id when the telecommuter calls even though, in fact, the telecommuter is not in the office or other nearby location
Even though Peter spent the day at home, none of his colleagues realized that he was telecommuting because his VOIP service allowed him to make phone calls where his office phone number would show up as the caller ID. Peter was mosting.

Alt: Even though Luis lives in Paris, Luis uses Vonage with a local Los Angeles phone number and caller ID so all his clients believe that he's in Los Angeles. Luis is mosting.
