<div>Im doing something similar for one of my customers. They currently have a 20Mb MetroE link for internet access and a 20Mb MetroE for site to site, I warned them about the amount of bandwidth needed. They prefer to saturate the Wan link than not have any VM at all for their remote site. </div>
<div>A pretty good guide which is what i used when I set it a while back is here:<br><a href="http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00807f8b70.shtml">http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00807f8b70.shtml</a></div>

<div>Its for Cm 4.x but it should still apply for newer releases.<br><br> </div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">I have a customer that is implementing a DR site across a 20mb/s MPLS network and we are trying to work out what voice services we can make redundant. I know that we can cluster CUCM server across a WAN link of that size, but according to the Unity Design Guides we shouldn't even consider trying to attempt Unity Failover without 100 or 1000mb/s. Is this accurate? Those requirements seem huge! Is there any way to try and provide a redundant Unity box across a network connection like this? We are considering just having a standalone Unity box over there that can split the mailbox load with the existing server, as well as having the Call Handlers set up on both of them so in the event of a failure the VM profile can be changed on the CTI ports to fail a main number over to the second server to allow calls to still roll in to the Call Handler. Does this make sense, or is there a better way to do this?<br>
