CME MWI interwork with CUE

Remember that CME signaling is SCCP in nature and using G729r8 while CUE only supports SIP and G711u.
To get MWI working between CME and CUE, perform following:

! dont forget the ever-important voice translation-rule

voice translation-rule 400
 rule 1 /^.*\(3500\)$/ /\1/
 rule 2 /^.*\(3555\)$/ /\1/
voice translation-profile TO-VM
 translate calling 400
 translate called 400
 translate redirect-target 400
 translate redirect-called 400
!

! enable SIP and H323 intersignaling

 voice service voip
 allow-connections h323 to h323
 allow-connections h323 to sip
 allow-connections sip to h323
 allow-connections sip to sip

 sip

  bind control source-interface GigabitEthernet0/0.230    ====  do not use Loopback0

  bind media source-interface GigabitEthernet0/0.230      ====  or MWI won't work

! add a dial-peer to make sure calls to VM is using SIP and G711u
