A speech-dialler would do the same job for you. You enter up to three
telephone numbers, your own and two close friends or relatives, and each has
to verify the call by pressing a preset number. The telephone numbers can
be to mobile or landline telephones, it doesn't matter, but the
speech-dialler must be plugged in to a landline socket, or hardwired, for it
to work of course.

If you know you are going to want a speach dialler in the first place,
you would be well advised to consider an alarm with one built in, where
it will be much better integrated into the alarm functioning than one
which is a generic add-on product attached to an alarm which wasn't
specifically designed to control or be controlled by a speach dialler.
