Unfortunately, when dealing with analogue lines, hacks are quite often
needed... I'd suggest that in this case something is causing asterisk (or
perhaps the card if polarity reversal is used) to fail to detect the fact
that ringing has ended or an answer signal has been passed when calling
these numbers... As such a timeout occurs...
You'd need to provide more information to pinpoint the exact issue... but...
the only real solution to getting reliable in call event signalling is to
use digital lines (or IP services that use digital lines or all IP) though
some analogue services do a better job using polarity reversals which makes
it much more reliable, the fact that these services are few and far between
makes that not an option for most...
