<p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt"><font face="Times New Roman" size="3">We use a load balancer for IP Phone services redundancy. There is no integration with any third party components. When I check our UC system, I found out that DNS client service is enabled on both CUCM and Unity servers which I don’t quite understand why is needed. The Services URL on CUCM is pointing to load balancer IP. Would there be any other reason we have to enable DNS client on CUCM and Unity server? Also is there a load impact by enabling DNS client service?</font></p>
