HOT TIP!
If you suspect the SPIDs given you are wrong, or the basic line provisioning
(configuration) is incorrect, call the Telco and ask them to verify the SPIDS and
provisioning from the switch.
They’ll probably need to have someone call you back. Verify this person is logged
into the switch. Get their fax number and fax them ZephyrExpress’ ISDN infor-
mation from the Appendix of this manual.
Sometimes the information in the Business Office computer is wrong. By verifying what
is programmed into the switch itself you can save time.

ISDN TIP!
In an emergency, to save a remote, you can sometimes get a line working with-
out the proper SPIDs or line configuration by dialing into it. This fix is only tem-
porary and the line will fail to initialize next time ZephyrExpress is booted.
Can you place a “pots” call?
From the dialing screen, change the
Mode
from
Zephyr
to
Phone
and try placing a call. Try
it on both outgoing lines. If you can place ordinary analog calls but not data calls, then
the phone company probably didn’t give you CSD (Circuit switched data) capability. The
line won’t work for data, and won’t carry high-quality audio calls.
The faxable order form in the appendix specifies CSD. Make them give it to you: it’s the
reason you specified ISDN.
Is your long-distance carrier OK?
If you can successfully call locally, but long-distance calls don’t go through, ZephyrEx-
press usually displays
Far end disconnect
,
No route available
, or
Incompatible Bear
Cap
as the ISDN “Cause” phrase.
You may try another by dialing the appropriate 10XXX prefix.
Some carriers and codes that we’ve tried are:
• MCI
10222
• AT&T
10288
• Sprint
10333
You must dial the full number, including the 1 or 011 + country code following the pre-
fix. You may program the 10xxx prefix into the
ISDN: Outside Line Prefix
field, but you
must remove the prefix before attempting local calls.
In our experience, other carriers are unlikely to be able to handle ISDN data calls. Let us
know if you find otherwise.
