Manage dial plan policies with AT&T Collaborate

As an administrator for the AT&T CollaborateSM service you can set dial plan policies for the sites that you manage.

Use dial plan policies to set the default length of extensions or to specify a site prefix that uniquely identifies a site.

A new user’s extension is automatically set to the last several digits of the user’s phone number, based on the default extension length. For example, if you specify a 3-digit default extension length, the extension is the last 3 digits of the user’s phone number.

A site prefix is a single digit or a string of digits that users must enter before calling an extension at another site. For example, if a user has the extension 234 and the site prefix is 12, callers from another site can dial 12234 to reach that user. This is helpful because users at different sites may frequently have the same extensions.
