<br></div>under ccmadmin for your MoH servers, do they all show as being registered? .. to what server? ...and can you confirm that we're specifically discussing unicast MoH and that that's the counter that you're looking at in RTMT?<br>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">This is also my understanding of how CUCM allocates the same media resource type within the same MRG. My lab is currently on 8.6(2)a and I’m unable to recreate the problem
– I’ve placed two calls, back to back, and put both on hold while having two MOH servers (MOH_2 and MOH_3) in the same MRG assigned to the called device MRGL. CUCM allocated MOH_3 for the first call and MOH_2 for the second call.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">Going to CCM SDI traces, do you see CUCM immediately allocating the same MOH server? In other words, is there a chance you might have missed previous MOH allocation failures
for your other MOH resources in the trace file? Do you see a <b><i>sendMohAllocateRequestToDevice</i></b> event for other MOH resources prior to the allocation of the overused MOH server?<u></u><u></u></span></p>
