Can I prevent certain types of calls being made with AOL Talk?

Yes. AOL Talk can set up selective call barring on your phone line, which blocks calls to any of the categories listed below. The AOL account holder (the person who holds the master screen name) can arrange this by contacting Member Services.

The following selective call barring options are available at no extra cost from AOL Talk:

• Premium Rate Services barring (bars outgoing calls starting with '09')
• International number barring (bars outgoing calls starting with '00')
• Mobile number barring (bars outgoing calls starting from '077' to '079')
  Please note: this does not include 'personal numbers' (which allow you to divert all calls to one number) starting with '070'.
