Possibly the best control is through nasty old Winmodems. This is way off a simple device for recording phone conversations, but anyway... When I was playing with Asterisk last December, I had heard that one of the PCI modems that Asterisk supports has an $8 OEM version. David Reid in York street has a bin where they chuck old motherboards, lan cards and anything else they want to throw out. I picked up a winmodem on the off chance. It seemed to be some kind of Lucent winmodem. I found some code of dubious provenance (the source looks undisguised reverse-compiled) called ltmodem from Pavel Machek. After some mucking around I got it to work. It can do full duplex, you can do your own dtmf detection, and the latency should be much better. Hours of fun for the socially deprived :) Jamie -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
