Hi! I'm looking for some help with hardware for a production setup of freeswitch. I need at least 150 concurrent calls, but would prefer to buy a server which can handle more to facilitate growth. I am looking at using the same codec (i think it is g711) for both legs of the call. I want to record all calls. Either to whatever codec and then transcode them separately or directly to mp3/ogg. I am going to use ESL to control FSW and also listen to most events over the socket. What would you recommend for hardware? Is it recommended to buy a sound card for transcoding or just buy enough CPU? I will probably run from SSD, record to same SSD or other local disk and continuously move recordings to external (network) storage. So: 150 concurrent calls ~10 initiations/second mod_event_socket - for control and events A limited amount of eavesdropping recording (either to original codec or ogg/mp3) Some "standard" modules.
