Tip
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 are in the USA or Canada and you do not know what protocol your line is configured for, try
Natl.I-1 first. If that does not work, see Section 5.5 for hints on how to guess your protocol.
