with one comment

Good ol’ Jerry from IBM wrote a nice post on the “Ask the Expert” forum with Ben Ng.  He came close to violating the NDA, in my opinion.  The wording of his questions help shed some light on the mysterious exam that I’m prepping for.

Here’s what I gathered:

  1. There will be three voice gateways on the lab (SIP, MGCP, and H.323?)
  2. The dial-plan section may be “small” on words, but big in configuration requirements.
  3. Understand configuration and impact of TEHO in the environment.
  4. Understand how codec selection and CAC interact with one another.
