What type of disconnect supervision does your service provider use on the type of line you are using?
What form of disconnect supervision have you configured in chan_dahdi.conf?
use callprogress=yes in your dahdi configuration.
The options he should be looking at are:
busydetect
and
hanguppolarityswitch
Although these depend on characteristics of the service provider.
