CCNP Collaboration 300-815 Book

Refer to the exhibit. An engineer is troubleshooting an issue where inbound Calls are failing after they transferred. The provider reports that update is not supported, and this is causing the calls to fail. Which command should resolve this issue?

Some users report poor quality when they travel to another continent and make calls. This issue applies only to one continent and not to others, where typically the dialing is fast and quality is clear. Users experience the same result at home when they call the same numbers in that specific continent. It seems like some users do not exist in the correct PSTN gateway when making calls to a specific country. The company is using TEHO to save on the cost of international or long-distance calling.

They are also using a globalized dial plan. What is the cause of the issue?

Refer to the exhibit. An administrator troubleshoots an issue where each user's 4-digit directory number is presented as the calling number when dialing out to the PSTN.

Which two types of authentication are supported for the configuration of Intercluster Lookup Service? (Choose two.)
