Question about audio in meetings

Question about audio in meetings

Can people in our meeting can talk "through" our computers (using the computer mic. & speakers) using Zoho meetings? 
 
If so, how do I set this up?
 
If not, what are some of the options for enabling audio through the computer (i.e. so they don't have to use a phone) and how do I do this? (please note, we are not in a country for the Zoho dial in/ toll-free phone number)
 
Many thanks!
