Show Suggested Answer

Suggested Answer: B, D

These two options are the benefits of deploying OAuth in a Cisco UCM environment that uses Cisco Jabber or Cisco Webex for on-premises calling. OAuth is an authorization protocol that allows users to grant access to third-party applications without sharing their credentials. In a Cisco UCM environment, OAuth allows Jabber and Webex clients to obtain access tokens from UCM after authenticating with their credentials once. The access tokens can then be used to access various resources, such as call control, voicemail, directory, and presence. The access tokens have a limited lifetime, but they can be refreshed using refresh tokens, which have a longer lifetime. This way, the users do not need to re-authenticate frequently and can enjoy a seamless user experience. Reference:

Option A is the answer, no doubt. It's like trying to catch a car thief by locking the garage instead of the car doors.

Setting up restriction tables for the international operator (Option C)? What is this, the 1980s? I think we can do better than that.

I agree, we should consider adding restriction table patterns for the trunk access codes.

Blocking international calls (Option D) is overkill. The question is about toll fraud, not international calling restrictions.

I'm not sure if restricting system transfers (Option B) would be enough. The question specifically mentions the need to block bypass attempts.
