At this moment there is a way to use some kind of hotdesking with a Yeastar S-serie PBX, but this is more a Yealink phone function in stead of a function that is provided by the PBX.
It would be a very good improvement to add this a a feature so that we can registed a device on the S-serie, and let the use choose what his extenion is by logging in using a featur code ( for example )
If this can be added, it will make it possible to use hotdesking on all types of phones, including softphones.
