Daniel,
"That depends"....oh, you SOB.
Whether you configure the Voice-port or dial-peer would depend on the
wording of question and proctor explanation.
You have 2 options: Voice-port or Dial-peer and you have 2 possible ends
on where to configure "no VAD".
The answers you need are:
Does the phone itself need to have Voice Activity Detection turned off?
Or When this physical phone receives any call, should there
be any data sent sent across LAN when no one is speaking?
-If yes, configure this that router's voice-port for "no VAD'.
When you dial a specific phone/phone number , do you need to have Voice
Activity Detection turned off?
-If yes, configure your router's dial-peer "no VAD".
Voice-port = phone is this router
Dial-peer = for calling phone on another router
