Yes, i'm currently playing with i4b to do exactly this. 

You use isdnphone to dial the number of the person to alert. To do this
reliably and with a feedback if the call succeeded, i have just commited
a kernel patch and a patch to isdnphone (adding the -w flag) to current.

In case the call succeded, you can play prerecorded messages or (as i do)
use rsynth from the ports (/usr/ports/audio) in conjunction with a patch
to rsynth (/usr/share/examples/isdn/contrib/hplay.c) to get a direct text
to speech output to an i4b telephone device.

After sending the alert message, close the call by using isdnphone -h.
