Look for the recent 'capacity testing' thread here. We've had some discussions on it, but so far the bottom line sounds like you won't be able to run more than 20 - 25 decent quality calls before asterisk dies.[snip]

Your statement relies completely on assumptions which may be incorrect. Transcoding significantly degrades performance, but without transcoding it may be possible for * to move dozens or hundreds of calls with H.323. See note below.

If the incoming and outgoing Codecs are the same, there is no "conversion" done. It basically becomes a packet relay, what goes in, comes out.
I'm not sure of the answer to your second question. However, your question actually begs a question I've been wondering about in the last couple of days:
I'm doing H.323 in, H.323 out....simple relay. (This is my customer's requirement...not my preference). What I want to do is ALWAYS use the same codec for the outgoing leg as for the incoming leg. In other words, if the call comes in as G.729, the outgoing call uses G.729 ONLY. If the incoming call is G.711, I want the outgoing to be G.711. I want to avoid any sort of transcoding.
Is it possible?
Thanks.

(FYI, Dual Xeon 3.06, 120 channels (60 calls) of above scenario, G.729 using less than 10% CPU!) (Remember, no transcoding is being performed)
