<div>I remember an Expressway 8.5 deployment once; on the inside everything was fine but on the outside, my clients would only ever register with one CCM node (although there were three discovered).</div>

<p class="MsoNormal"><span style="color:#2F5496">It seems that our phone services Via MRA are somewhat intermittent, It seems that the clients are trying to register with CUCM servers that are not running the CCM service. When I check servers under phone services
the client seems to get a different pair each time the application is launched. When the servers reference the one of the two servers running CCM phone services connect. When a CCM server isn’t referenced phone services fail to connect. Thought I’d just check
here before opening a Tac case.</span><o:p></o:p></p>
