<div dir="ltr">I would concentrate on the disk side of things with a good stripe or RAID of SSDs. Or, just add enough RAM (say 64GB) and make a large enough tmpfs/RAMdisk partition to store your recordings before transcoding and shipping them off to the storage server. Just make sure to have UPS backed power. <div>
Can the transcoding be done on the storage server (they usually have lots of spare CPU cycles)? Separate network adapters for VoIP and storage would also be good. </div><div>I would go with a CPU with 4 cores.<div><br>
