The diald manual page states that impulse is used to keep the line up
for some duration, to save on line charges.
The current behavior of impulse will unnecessarily bring up the line
-- this will *increase* line charges. This implies that the current
behavior is not the intended behavior.
Or, perhaps you're saying that if you're charged in 15 minute
impulses, and you make 5 calls in that interval, then they all get
charged as if they were a single 15 minute call? In that case,
impulse is working correctly, and there is no bug.

Here's what happens:
I set my impulse up for a long time (say, one month). I bring up the
line. I let the system sit idle for a few hours. I verify that the
line is inactive by watching the modem lights. I disconnect the
modem. I see messages in the log indicating that diald is trying to
redial.
Aside: I have this line in /etc/syslog, to make it trivial to monitor
messages without any unnecessary system activity:
auth.*;daemon.*;mail.*;news.crit;news.err;news.notice;*.=debug;*.=info;*.=notice;*.=warn;cron.none |/dev/tty9
I first performed this experiment on a laptop which had no networking
daemons running (and, with no users logged in). If diald didn't have
the impulse command in place, it would not bring up the line, even if
I left it idle for several days.
