Hi, Zoa,

yes, these calls are from SIP to SIP. We will have more than 3000 (more like 5000)concurrent calls come into system and we will need to handle them.

What exactly do you do with these calls?

We will also need an IVR function as well.

I am not up to speed on Asterisk yet, so, I am a little bit confused by all the different ways of doing it. Someone is talking about IAX: I think it can only be used between Asterisk servers, right?

In this particula rscenario we are getting calls as SIP directly from carrier, so we will not need to do any conversion (I think). We just route the calls to the destination, that's it.

If you are just handling SIP signaling and routing a solution such as SIP Express Router is much more appropriate than Asterisk for this kind of volume.

Any suggestions on how to proceed? Can Asterisk do it?

I read somewhere that it takes about 30 MHz per one voice channel, so if we want to have 5,000 calls, we will need 150,000 MHz? Thats like 50 3 GHz machines... Not going to fly with our people.

It depends on what you are trying to do. If you are transcoding 5,000 simultaneous calls, it's going to cost a lot of money, wether you use Asterisk or not...
