I'm doing ramdisk recordings of about the same number of streams you're talking, in 4GB. I move out completed recordings once every 15 minutes or so via NFS, and as such, I never use very much of the ramdisk. There's no rule that says you have to use the whole 4GB of ram for recordings. I'm probably staying below 100MB or so. Strictly speaking, I'm using both ramdisk and external server, but the external server is just a centralized system with larger disks. However, I know that this arrangement isn't working for my load which is about to double again, so I'm upgrading to better hardware (and maintaining the status quo with my asterisk arrangement) If you read every single title of asterisk-users in the last few months, you'll find a similar discussion on this topic which went through the pros and cons of ramdisk versus centralized server. Somebody at that time mentioned particular names of programs that can do the centralized recordings by doing network hardware level replication and picking off the SIP packets. I've never done this, but if you find that mailing list thread you'll be able to find names of people who say they've done that. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
