We have a 3 call manager cluster and the if I shut down the subscriber that this site is registered to then all the phones will register to the other subscriber but when I place a call to the phones I get destination out of order on the debug, I have dial peers for all three call managers in the config, however if I were to just stop the call manager service on the subscriber and not shut the server down then I can place calls to the phones fine, it would appear that when the subscriber is not on the network then the calls don’t go through. Has anyone seen any issues like this before.</SPAN></FONT></P><DIV><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt; font-family:Arial"> </SPAN></FONT><BR class="khtml-block-placeholder"></DIV><P class="MsoNormal"><FONT size="2" face="Arial"><SPAN style="font-size:10.0pt;
