First, version 11.5 has reached its End of Life, and it’s highly recommended to upgrade to the latest version. From what I understand, your requirement is as follows: when you call a desk phone user and they don’t answer, you’re looking for a way to notify the desk phone user via email about the missed call.
Instead of this approach, why not have the user use a softphone , such as Webex app or Jabber, on their mobile device? This way, they can answer calls directly from their phone, and if they miss a call, they can return it immediately from the same device without needing to check an email notifying them of the missed call.
Alternatively, you could set up Single Number Reach, which would allow the user’s mobile phone to ring whenever someone calls their desk phone.
If a caller leaves a voicemail when the call isn’t answered, the user can be notified via email, as @Jonathan Schulenberg mentioned in his reply and not for the above case.
You Could do that on Single Number Reach where the call Rings on mobile phone. But Not on Jabber.
Thank you for sharing this, @Jonathan Schulenberg . I’ve never explored this option in the CUC before.
CUC is as CM a virtual server. So you'll need to create one or two if you wand redundancy VMs based on the OVA for the CUC version you intend to setup and then run the installation of the CUC from a bootable ISO.
