[cisco-voip] Jabber/CIPC and QoS

[NateCCIE]

Or take the most approach of do nothing.

My personal favorite is to use codecs where QoS matters less, like iLBC, OPUS, etc. 

So many business are getting rid of the QoS capable WAN and just doing VPNs, even if they have fancy names that make it sound better than public internet.
