[cisco-voip] Redundancy -- Quality of Voice -- QoS vs RSVP

[Robert Kulagowski]

Blind-leading-the-blind here, but when I looked at RSVP it was still
built over the underlying routing protocols.  If there are two links
into Site B, RSVP is still going to say, "OK, there's a path to Site B
over link A".  "Does Link A have bandwidth?"  If yes, great.  If no,
then the call "fails", even if there was bandwidth available on Link
B.
