The phone module is rather big – it is actually divided in to three parts:
- Phone Models
- Phones – like assets – the individual phones
- Phones to extension to DID to employees
Now – you do not need to use all of them in combination – most interesting might be the Extension to DID tracking for just in case – but you can combine them completely and track each phone and DID and extension with the actual employee.
There is not much to explain here – it is kept rather simple but allows to document a lot. If you have multiple sites and phone switches, you might need additional fields that not yet exist. You could also abuse the description and notes fields for this purpose.
