Has anyone ever thought configuring asterisk on a pair of pc's to act as remote broadcast terminals for the broadcast radio industry? Seems like a stripped down asterisk on a laptop with a PCMCIA ISDN modem connecting to another asterisk instance on a PC at a radio station would work nicely. Use one of the higher quality codecs, interface the remote mixer to the sound card on the laptop, and the studio pc would hook to an unused input on the studio's mixer console (after going through the delay of course!). Write a small TCL app to sit on the laptop and interface to manager, and you'd be all set. Is this overkill for asterisk, is there something better to do this task? Nik
Why? Just use shoutcast/icecast for that.

Hi Nik,> Does shoutcast run across isdn?Shoutcast, like its commercial counterparts, runs on an IP network. You can: 1) use an ISDN modem (PCI, or PC card) that plugs into the PC, or 2) use an ISDN TA that connects via a serial port, or 3) use an ISDN router, connected via Ethernet to the PC. For AM monaural broadcasting, almost any setup should have adequate quality. For FM stereo, try to get a 128kbps (both B channels, transparent) connection. If you are limited to 64k or 56k, and will be broadcasting music, IMHO Windows Media Encoder or RealProducer will give you better quality. These are freeware but not open source, of course. Be aware that many laptops don't have a "line in" jack, and the microphone connection is often noisy and/or mono. If high quality is important, use an external A/D such as Extigy. --Stewart
