[cisco-voip] requirements for WAN link with centralized deployment

[Lelio Fulgenzi]

Thanks. I should have said that I am reading through that as we speak and was looking for anything that might not be included there. 

I could have sworn there was a command line utility that you can run on the router that sends data back and forth to a stub on another router and it tells you if it passes voice quality link testing or something like that. I've never seen that in the SRND.

  Look in the Cisco IP Telephony Solution Reference Network Design
  (SRND). It's in the section called "Clustering over the WAN". That's
  probably a very good document for you to read through prior to making
  any decisions.
