Restricting analog calls
Generally, most of the activity on the ISDN line will be created by data traffic. That is why the most of the settings in this section are targeted at data calls. However, in some cases, you may want to place some restrictions on analog use of the ISDN line.
Each phone port has a type of calls setting which you can use for cost control purposes. It allows you to restrict traffic as follows:
•allow incoming calls only
•allow outgoing calls only
•allow all calls
•do not allow any calls
To restrict analog calls
1.On the Manual Configuration menu, click ISDN and phone ports. The DIVA LAN ISDN Modem displays the ISDN parameters page.
2.Select the phone port you want to restrict calls on. The DIVA LAN ISDN Modem displays the ISDN phone line parameters page. For example:
3.Set the Type of calls supported parameter.
4.Click Save.
5.Click Reset.
