A friend worked on a project for a national technical support service a couple
years ago. He said that for the touch-tone interface to non-alpha pagers, the
sequence of beeps and timing varied widely, not only between pager companies,
but sometimes on successive pages to the same service and even the same beeper.
He eventually found commercial voice-mail hardware system that had enough analog
hooks to support reliable software, but it was pricey ($5-10K I think.)
There is a kludge for those of us who just want a reliable notice to a
numeric beepers. It's useful if you just need to know that you should
check-in, with little other info. Dial the beeper, pause for the minimum time
for the message prompt, and repeat a short signature at short intervals,
as in "91,,91,,91,,91,,91". Whatever the timing or promps, some of it
will get through, an you'll get a recogizable code.
It's not elegant, just quick and cheap appropriate technology for those with
a simple need and other obligations.
