<p class="MsoNormal"><span style="color:#2F5496"><o:p> </o:p></span></p>
<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.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#2F5496"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#2F5496">The problem seems to be that when we log in via MRA the jabber client is attempting to register will any two of the 9 CUCM servers. It only successfully registers when one of the two servers are one of the one
running CUCM. Presence and directory services (UDS) all ways register with the correct servers<o:p></o:p></span></p>
