5. Click the ‘ISDN Port’ link to bring up the ‘ISDN Port Parameters’ page.
6. Specify the switch type.
7. Enter your ISDN phone numbers in the ‘Numbers’ area. If you only have one number,
enter it in both number fields.
8. If you know the billing intervals for your ISDN line, enter them in the appropriate fields.
The ‘Initial Billing Interval’ is the minimum amount of time you want an ISDN channel
to be open. The ‘Recurring Billing Interval’ defines the minimum amount of time you
want an ISDN channel open after the initial billing interval is surpassed.
These settings help keep the ISDN line from being opened and closed too frequently,
which could reduce your ISDN charges, depending on how your provider charges
for your ISDN line.
For example, a provider may charge 25 cents to open a B-channel but only 10 cents
per minute afterward. If the channel is opened and closed frequently within a few
minutes, your charges for opening the channel will outweigh the charges incurred if
the channel was left open.
9. Click the ‘Save’ button.
