I’m not sure of the correct terminology for what I am looking for so hopefully I can make some sense here.
Currently have some Cisco 7975’s connected to a UC540.
The extra buttons on the phone are configured to watch the state of other extensions so that the user knows at a glance if the extension they wish to call/transfer to is busy.
Is it possible to do this sort of thing with FreePbx?
Is it a function of the SEPxxxxxxxxx.cnf.xml file or something on the server or a bit of both?
Thanks,
Brian
