Table 16 describes situations that you may encounter when
using the HST-3000 to test ISDN PRA service, and then helps
you resolve the situation.
Description
You will not hear a dial tone
when you place voice calls
from the HST using enbloc
dialing or if you place data
calls. This is normal for
devices placing ISDN calls.
When placing or receiving a
call on the HST, you want to
verify that the call is con-
nected.
Calls may not connect
because the HST is not con-
figured properly for the out-
going call, or for a variety of
other reasons, such as an
invalid bearer capability
("Call Service" on the Call
settings page).

Resolution
N/A.
Check the call status on the
Phone screen or the Inter-
face screen.
Verify the following:
– Make sure you specified
the number you want to
call as the Called
address (under Call Set-
tings); not your Own
Address (under ISDN
settings).
– Make sure you specified
the correct call control
protocol (under ISDN
Settings).
– If the HST is configured
correctly for the call,
check the cause code on
the Phone screen.
