.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. What should you configure before entering auto qos?
Call Simulator. You can use to validate path from router to the PSTN.

2. When configuring a Gatekeep-controlled trunk - what do you do with the <i>Wait for Far End H.245 TCS</i> option?
1. Complicated Hunt Group|2. Need to support Calling Name|3. Need to support Call Park Call Pickup
Gatekeeper - zone local GK cisco.com 10.1.6.1 - zone local CUCM cisco.com invia GK outvia GK - zone local BR2 cisco.com invia GK outvia GK

Uncheck it! Otherwise both H323 devices on either end wait for the other to send TCS first - and the connection will timeout.
3. Maximum Wait Time for Desk Pickup?
#test voice translation rule 1 <input to test>

47. Describe how you configure SIP URI functionality.
The + character is not supported on a VOIP dial-peer.||So you'll need to add back on the POTS dial-peer before it gets to the PSTN via a voice translation-rule.
Sends the Calling Name.
Top Down means that channel 1 will be the first channel used to place outgoing calls.

Sends every digit to CUCM in real-time with digit-analysis being handled by CUCM.
