anyone have any comments with respect to the dsp calculator results and what
 the difference between optimized vs normal results is?

what's the difference?

compare the "CLI info" given by the DSP Calculator

the optimized result uses the "codec complexity flex" on the voice-card
the normal result uses either "medium" or "high" for the codec
complexity depending on the codec you like to use the DSP for.

difference between flex, medium and high:

Thanks. I was aware of the CLI difference, but not what they actually meant.

I'll read up on that, but suspect because I'm only using G711 that I'll be O
K using the flex calculations.

More questions on the DSP calculator:

Given a 3845 router, 24 ports of FXS on EVM, 8 ports of FXO and 6 PRIs,
what's the best combination to achieve this?  If you just do everything
"straight", I think you run out of DSPs on the router.

However, if you do NM-HDV2s (which have their own DSPs and can do 2 PRIs
onboard + have a daughter card for VWIC2-2MFT-T1/E1), it looks like it's
doable.

However, I'm not sure what to fill in for some of these fields.
In NM 1, NM-HDV2-2T1/E1, two onboard T1, and a VWIC2-2MFT-T1/E1, max
calls is 96, which makes sense.

But when I'm filling out that line, I've got G.711 column (which I'm
assuming is low complexity), then G729a (medium) and then G.729b (high?)

Would you put in 48 / 48 for G.711, or are you actually trying to
predict how many of those calls need to traverse a G.729 WAN, so you'd
do something like 36 / 12?

And in that case, what do you do on the next page when it asks about
transcoding sessions?

For conferencing, you're putting in the number of 8-person max
conferences that you'd like to do on the router, right?

HW MTP is only used for SIP trunks, right?

IP SLA I understand.

Thanks, Bob
