The Infinity 5000 series phones running XSTIM firmware will operate similar to a Nortel phone. Extension configuration is performed on the UCX and the behaviour of the phone follows settings configured under XSTIM Settings and XSTIM Properties.
There are a few exceptions and this page will provide a description on the differences.

| XSTIM Properties | Description |
