IMPORTANT!
Each ISDN Line has a certain ISDN protocol (or “switch type”) which the phone
company should have given you. By far the most common protocols in the USA &
Canada are National ISDN- 1 & National ISDN- 2 in which case you should set the
Telco setting to
Natl.I- 1
.
If you do not know what protocol your line is configured for, try
Natl.I- 1
first. If that
does not work see section 7.3.2 for hints on how to guess your protocol.
