We are running CUCM 7.1.5 and the trouble is with load balancing the Extension Mobility service. We are using F5 LTM's and we have created a pool and a virtual server to handle extension mobility login requests. When we point the Extension Mobility service URL(in CUCM> Device Defaults> Phone Services)to the VIP, we get an error "Host Not Found" on the phone. Since we have never set this up for Call manager, we are using an existing web server configuration as a template, but i'm not sure if we have to configure something specific, there didn't seem to be alot of options when configuring, unless we have to create a specific "iRule". If anybody has configured this with an F5, and there is a gothcha in the setup, or if a special irule is needed, I would greatly appreciate the help in getting this working. Thanks in advance for the helpful suggestions... <o:p></o:p></span></p></div></body></html>
