You might want to look around the wiki (www.voip-info.org) as most of 
your questions have answers there.

> 1- No RTP only singnaling, Is it possible?
> Ans:

Yes, but probably not 100% likely. If any of the 1000 users have their 
equipment behind firewall/nat boxes, you're likely to end up handling 
rtp / transcoding. Also, depending on the exact equipment used by the 
1000 users, not all devices support g729. And, any local calls 
terminating via analog or PRI pstn lines will likely be g711 only.

> 2- How much RAM?
> Ans:

Since memory is cheap, through a couple of gig at it.

> 3- How much bandhwidth per month with G729
> Ans:

Rough answer... about 30 kbps of bandwidth per g729 call. Therefore, 100 
simultaneous calls times 30,000 equals 3,000,000 bps. (That's roughly 
two T1's, or 30% of a 10 meg ethernet, etc.)

> 4- Proccessor?
> Ans:

Any... really doesn't make that big of a difference whether its AMD or 
Intel. Plenty of examples on the wiki.
