CCIE Voice Test

Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
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. In CME Where is the Calling Name derived from?
AAR -- Used for WAN Congestion|SRST -- Used for WAN Outage
The name configuration field in ephone-dn and voice register dn
Assign a logout-profile to the ephone.
CUCM Service Parameters --> Call Park Reversion Timer

2. If you have an H323 Gateway at a siet where the phones are controlled by CUCM - what do you need from a dial-peer perspective?
Allows you to transfer by only pressing the Transfer button once.
You need pots dial-peers for incoming calls and you need a voip dial-peer pointing to the CUCM so the H323 GW and connect the call to those phones.
Mobile Connect
Dtmf-relay h245-alpha

3. How do you test a Voice Translation Rule?

4. On an MGCP GW - if you select Top Down under Channel Selection Order - What does that mean?
You need pots dial-peers for incoming calls and you need a voip dial-peer pointing to the CUCM so the H323 GW and connect the call to those phones.
Outbound dial-peers
Sh ip rsvp reservation||sh sccp connections
Top Down means that channel 1 will be the first channel used to place outgoing calls.

5. How do you configure SIP phones to be able to call other SIP phones via SIP URI?
Translate called - Calls going out to the PSTN||Translate Calling - Use on calls coming in from the PSTN. To change the ANI (Caller ID)
SIP Route Pattern over a SIP Trunk.
Sh ip rsvp reservation||sh sccp connections
Allows you to transfer by only pressing the Transfer button once.

6. What do you need to do to activate the CME GUI?
Automatically configures the MGCP GW for you.
Debug isdn q931
Find the GUI Files - show flash | i .html|ip http server|ip http path flash:/<PATH TO FILES>||telephony service|web admin system name admin pass cisco|dn-webedit
Uncheck it! Otherwise both H323 devices on either end wait for the other to send TCS first - and the connection will timeout.

7. How do you see multicast packets being sent?
voice translation-profile|and|voice translation-rule
Translate called - Calls going out to the PSTN||Translate Calling - Use on calls coming in from the PSTN. To change the ANI (Caller ID)
Debug ephone moh
#show call active brief|#show voice call summary|#show voice call status|show dialpeer voice summary

8. How do you allow H323 calls to be preserved should the primary H323 GW fail?
