This question is more directed at everyone in this thread. How is this certification, and the CCNA/CCNP Collab, perceived in the industry? Is it worth investing time in getting a VoIP certification? Will it give me a competitive advantage? Or, is VoIP something that most network engineers are just expected to know.
I think you can apply the same logic from the other CCNA certs. Certs with no experience is not super useful. Experience without certs is good. Experience with certs is best.
Cisco just revamped the Voice/Video certification track into Collab without the dependency on CCNA R/S so I think that should indicate how the industry is evolving in a general sense.
