I assume you mean "23 agents each talking to one other person", not
"23 agents each talking to 23 other people".

The answer is yes, assuming you have sufficient bandwidth on the IP
connection. I have heard that some high compression codecs (like
G.723.1) may cause stress if you're using it all day long, and also
may noticeably degrade the way your voice sounds.
