Keypress can be used for various reasons, but there is one situation when it should ALWAYS be used: When a cell phone forward is in use.

When that cell has no signal or battery issues it sends calls to its personal cell voicemail, keeping departments or users from answering business calls. This can be a detrimental loss to all kinds of businesses.

Suggestion: A popup notification when a number is added to cell/landlines. "Is this a mobile number?" Y/N "Saved! (Mobile Keypress has been enabled.)"

Unsure how detailed we should be with how it saves calls/protects business. Listing it as a need is probably the best way to add this client saving function.
