We recently deployed a UC320 system in a Dentist office. 1 Phone (SPA504G) is in a treatment room where they use sedation and the patient is semi-conscious. We need a dedicated button on the SPA504G for dialing 911. When I attempt to program one of the four buttons for "external", it requires a 9-digit #. It would be nice if we could dial 9911 from a hard button.
Other 911 issue: On some other IP phone systems, 911 is a reserved command, and you are not required to dial a 9 first. I cannot find a feature like this, and would offer that if someone dials 911, the system automatically (or through enabling this in software) will get out to the emergency number. I can think of some cases where a lot of international calling is being made, where it may be possible that someone needs to dial 9+11+...., so I believe it should be a "checkbox" type option.
Maybe I have overlooked the solution for both of these?
