FYI 

Zoom tech support has confirmed that poly vvx-350 a 6 line phone  (with pro lic) will only do 3 "ad hoc" audio conferencing calls.  They are contacting poly support to see if Poly has a template to work around this issue.  Zoom Client doesn't this 3 ad-hoc con call limit.  It can do up-to 10.
