This call form page uses hidden SubGroup fields to specificy which of the allocated telephone numbers should receive a WebCallback call. Again the default error and success page names are used. The SiteId hidden field specifies which site's numbers should be called. Until you edit the SiteId field this form will call GlobalPhone.
Because each form has its own SubGroup value the form can call only one of the defined subgroups. Remember, though, that a subgroup can have several lines allocated to it, so subgroups can be used to specify calls to individuals (with precisely one number each) or groups like departments (where several numbers might be allocated to a single department).
This technique is probably best suited to a situation where the different individuals or departments each have their own page or set of pages. See other examples for a single form used to call a number of different destinations.
