To address several points: OrecX (http://www.orecx.com/) can do call recording outside of the Asterisk core using several different methods depending on your needs and channeltypes. In fact even with Sangoma TDM cards you can capture audio at the kernel level and send the audio as RTP streams very efficiently(3% CPU load for 92 channels) to an OrecX server on your network. It must be mentioned that setting up Orecx with retrieval might be a little complex for some Asterisk users, especially if you are recording a large amount of calls, or are recording on more than one Asterisk server, and if you choose this route you would do well to hire an experienced consultant(or contact Oreca directly) to do the install for you. As far as Asterisk-based recording, writing to a RAM drive(or tmpfs) is about your only option if you are planning on doing more than 50 concurrent recordings, if you are using Asterisk it is a viable and tested solution. I have several client systems that are recording well over 50 calls concurrently on a daily basis this way. If you will be recording directly to hard drives with any frequency or volume I would strongly recommend NOT using standard IDE or SATA hard drives, they burn up and fast. Use a caching SCSI drive controller with some high quality SCSI drives and you can record to those drives for years even at 40 concurrent channels recording all day every day. Hope that helps, MATT--- _______________________________________________ -- 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
