You have a Skype for Business Server 2015 environment. All users are enabled for Enterprise Voice. You have a Microsoft Exchange Server 2013 organization that contains one server named EX01.
You plan to implement Unified Messaging (UM). From Skype for Business Management Shell, you run the following commands:
New-UMDialPlan-Name UMDialPlan-UriType "SipName" ""VoipSecurity Secured ""NumberOfDigitsInExtension 4 ExchUCUtil.ps1
From Event Viewer, you discover the following error message when Skype for Business Server 2015 attempts to transfer a call to UM: "Attempts to route servers in an Exchange UM Dialplan failed. No server in the dialplan UMDialPlan accepted the call with id [03b5ba2bf7ec4663bc43e8e49c246634].

You need to ensure that the Enterprise Voice users can receive voice mail.
