If you have UCM software conferencing resources and IOS hardware conferencing resources in the same media resource group (MRG), which one will be utilized first? Will they be used in the order that they are listed in the MRG?
Thanks in advance,
You are right in that having two seperate MRG's in an MRGL will allow you to determine which resource is selected first. Because the MRG's in a MRGL are in a prioritized order, you may put the MRGs with the software conference bridges above the MRG's with the hardware conference bridges to achieve your stated goal.
From a best practice standpoint however, it is generally accepted that where hardware resources are available, use those first before utilizing the software resources that are native to the CallManager. The argument being that using software resources takes away cpu cycles from other functions such as call processing. In the same vein, given the central role that the publisher plays in the cluster, if possible, avoid stressing it beyond its 'normal' functions.
Does this answer your question?
