[cisco-voip] RTP and Bluecoat

[c3voip]

We have Riverbed, and I just let the voice subnet pass-through.  No point
trying to optimization connections that really can't be optimized.
Especially when you are talking about a limited number of connections that
can be optimized, I like saving those for MAPI and CIFS connections J

We've run into a bit of fun with WAN Optimizers, not vendor specific though:
1. extra delay/latency.  must consider the added delay and latency for
signaling and media thresholds especially related to user experience
2. preservation (or not) of DSCP bits.  we've encountered several WCCP
engines that discard the DSCP bits and thus loose all QoS.

Generally not a good idea for media or signaling traffic for setting up
media.  Of course it can be made to work with careful planning and
observation depending on your resources and motivations.

Does anyone have any experience good/bad or indifferent regarding running
voice rtp traffic through a blue coat wan optimizer? I personally don't care
for the idea, but it seems the situation has came up and I'm wondering if
you folks have any best practices, gotchas etc, those of you who have done
it in the past.

Thanks in advance
