hardware recommendation

[mechx]

Please recommend hardware for an outbound 120 seats call center. line to agent ratio 1:1, outbound trunks 4 PRI E1. I plan to use ulaw for least transcoding, since there is no bandwidth issue. Full Recording. Thanks in advance.

3 x Quad-core CPU 8GB RAM, Sangoma a102 for ViciDial/Asterisk
1 x Dual Quad-core CPU 16GB RAM, SCSI/SAS RAID 10 for Database
1 x Quad-core CPU 4GB RAM for web server
1 x big archive server to store recordings

Thanks. tottaly forgot to mention, plan to go 500 seats. Any consideration and/or update in your recommendation. Also about sangoma card should I go for hardware echo cancellation?

[mflorell]

If you are planning on going to 500 seats you will want the most CPU cores and the most RAM that you can find in a database server, or possibly a 6-server MySQL cluster. You will want at least 3 web servers and probably 10 ViciDial/Asterisk servers as well as a cluster of archive servers if you want to keep those recordings for very long.

mysql clustering is doable in vicidial environment now?

Master and slave right?

[mflorell]

Not talking about master/slave, I'm talking about MySQL cluster(minimum 5 servers required). We have never set one of these up, but based on the specifications it should work.

As for Master/Slave, we have set these up several times for clients. Works fine with ViciDial.

Cool

Reading on it now.
