Hi, I want to use different pulse audio hosts as different senders and recivers. So, sometimes I want to send from my local micro to Host A, sometimes only to Host B, sometimes to both (multicast). The function I need is something like a push-to-Talk script, or one commando line tool to intiate a call to a other host. I used paplay to distribute sound files; but is there also a easy tool like this to distribute sound from my mic into the LAN? And when I finished I want to stop the call. Like a simple phone with nobody who have to acknowledge the call. Something like #: pasend 192.168.1.12 exit The other question is, that I want to know which method you use for prioritise the IP-packets. Layer 2 with 802.1p or Layer 3 with DiffServ/IntServ? thanks, Max -- "Ein Herz f?r Kinder" - Ihre Spende hilft!
