NEW QUESTION # 89
You have a Teams Phone deployment that contains a branch office.
You need to restrict toll bypass for a user based on the office in which the user is working during an inbound or outbound PSTN call.
What should you use?
- A. dial plans
- B. Local Media Optimization
- C. a calling policy
- D. a voice routing policy
- E. Location-Based Routing
Answer: C
Explanation:
Calling policies in Teams
In Microsoft Teams, calling policies control which calling and call forwarding features are available to users. Calling policies determine whether a user can make private calls, use call forwarding or simultaneous ringing to other users or external phone numbers, route calls to voicemail, send calls to call groups, use delegation for inbound and outbound calls, and so on.
You can use the global (Org-wide default) policy that's created automatically or create and assign custom policies.
Calling policies include:
* Prevent toll bypass and send calls through the PSTN
Turning on this setting sends calls through the Public Switched Telephone Network (PSTN) and incur charges rather than sending them through the network and bypassing the tolls. This setting is off by default.
