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. How do you allow the Calling Name to be sent to the PSTN on a router?

1. Complicated Hunt Group|2. Need to support Calling Name|3. Need to support Call Park Call Pickup

3. How do you set up redundancy on outbound dial-peers on an H323 gateway?
Region setting alone is not enough. You must set:|Enterprise Parameters --> Advertise G.722 Codec Disable
(config)#voice register dialplan
#voice-class h323 1|#h225 timeout tcp establish 3 (if no response within 3 seconds continue dial-peer hunting)
SERVICE PARAMETER>|| Stop routing on unallocated number flag - Set to False|| Stop routing user busy - Set to False

TRUE
Phone number followed by domain name.|i.e. 3006@ipxcme.com
When multiple sites use the same route pattern - do your digit manipulation on a route list.
Create 2 voip dial-peers - one the Sub and one to the Pub (the Pub with a preference of 1). Then create a voice class h323and set the h225 timeout value so it will hunt between the two.

43. 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?
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.
