Customisation Being able to customise the client ring tone would be great. However a central customisation is sorely needed, these softphones are used in business, there must be a simpler way to provide complete management of things like codecs and client behavior (like focus and ringtones). Ideally from the PBX but as a start having it able to be managed via group policy on windows would be good. The current methods to provide central customisation are all workarounds and hacky Toast Notification It would be great to be able to enable the "Toast" notification on the bottom right of your primary monitor while the client is running. The focus option on call is very intrusive to the user and a toast would be far better. 3CX phone has this function already however it only seems to be active when you have closed the client with an X and it is running in background? Call path headers When a call is forwarded from another extension by ring timeout/forward setting, have the inbound call forward through the extension it has come from. Better display of CLID information Make the client have more lines and a smaller or adjustable font. A lot of the information presented to the client is lost with the current amount of line real estate available. UX A general polish on the client would be nice, the UI is a bit dated when comparing to other UC clients. Even being able to resize would be nice, having a fixed size provides limitations around usability for things such as presence listings, directory and caller information.
