Skype for Business, How to forward calls, redirect calls, and use simultaneous ring
The Microsoft webpage https://support.office.com/en-US/article/Set-Call-Forwarding-options-in-Skype-for-Business-1ec2e7fb-471c-4c35-bc90-a35991b3f532 outlines the steps for turning call forwarding and simultaneous ring on and off.
How do I forward or redirect Lync calls or simultaneously ring another number?
Please note that these options will only be available if the customer has Enterprise Voice enabled (the customer can check this at http://uc.illinois.edu/MyUC). Certain calls may not be able to be forwarded based on the customer's calling restrictions (for example, you can't forward to a long-distance number if your NCOS is community calling only).
