In times of an emergency a help phone must be simple to use as unrestrictive as possible. A hands-free phone only needs the user to press a button once, even if they were injured or disabled it is easier to press a button than to hold onto a handset.
The user needs feedback that the phone is connecting them. A push button with travel will let them know so they know it has been pressed. Both visual and audible feedback is important to indicate that a call has been placed. A delay in any feedback would appear as an eternity in an emergency situation.
In relation to using a handset the cord length determines the restriction to a users movement and means only one hand is free. The hands-free user has the flexibility to use both hands. This then allows the user to do other tasks such as: applying first aid, directing traffic, taking notes or even receive instructions to fix a car with their head under the bonnet which could be even more important for remote locations. A hands-free help phone should be able to operate in the expected maximum noise environment.
