<span style="font-size:11.0pt;color:#1F497D"></span>Which phone model do you use? 192.168.33.90 doesn't belong to <a href="http://192.168.23.0/24">192.168.23.0/24</a>, so the first thing that i will be doing is check routing tables on the phone. Or for more help you could draw you network layout and poste here.<br>
