Final answer:
Whether users in the 'International Dialers' group can always dial internationally depends on the group policy set by the administrator and can be influenced by various factors such as technical limitations, service outages, or cost control measures.
Step-by-step explanation:
The statement that 'Users in the International Dialers group will always be able to dial internationally' may not necessarily be true without more context. In computing and telecommunications, user permissions and capabilities are typically managed by an administrator. The capabilities of a group such as 'International Dialers' would be defined by policies and rules that govern their level of access. For instance, if the group policy is set such that it allows members to dial internationally, then the users will have that ability. However, there can be other factors that affect the users' ability to dial internationally, such as technical limitations, service outages, or cost control measures. Hence, being a member of such a group does not inherently guarantee the ability to dial internationally at all times.
