HOT TIP!
Most phone companies in the USA have settled on a standardized SPID format, based on the
telephone number. This format is area code+7 digit phone number + 0101. For example, if
your phone number were (321) 555-1234 then your SPID would be 32155512340101.
However, numerous formats were used in the past so older lines will probably be different.
For a list of known working SPID formats, listed by telephone company, see Appendix 1.

ISDN TIP!
In an emergency, to save a remote, you might be able to get a line to work without proper
SPIDs by dialing into it. If it works, this fix is only temporary, and the line will fail to
initialize next time the Zephyr Xstream is booted.

ISDN TIP!
If you see SPID ERROR as your line status, your SPID for that channel is incorrect. In this
case, check the SPID. For a list of known working SPID formats listed by telephone company
see the Appendix. Section 13.4.5 (Deep Tech Information) has additional ISDN
troubleshooting information.

TIPS ON SPIDS
1. Incorrectly entered SPIDs are the most common problem USA users have placing ISDN
calls. Compare the SPIDs you have entered with the SPIDs provided to you by the phone
company to be certain that you have entered them correctly. Do not add anything to your
SPIDs.
2. Note that there are no hyphens, dashes (-), or spaces in SPIDs, so the system will not allow
you to enter any non-numeric characters. If your installer has included them in the SPID,
ignore them.
3. For a list of known working SPIDs by Telephone Company, see the Appendix 1.
4. If you have any questions about your SPIDs, call your phone company.
5. If you have AT&T Custom Point-to-Point or Euro-ISDN, you should not enter anything in
the SPID fields.
