Hello! I'd like to Flash() a modem line (BRI) with Asterisk. It is a passive ISDN-card connected to a hardware PBX. I use ISDN4Linux. I recognised that unfortunately the Flash() application flashes Zap devices only. Now I am wondering how I could flash Modem/ttyI0. The source code chan_modem.c doesn't contain anything about flashing a modem line. So I tried to simply put the AT-command sequence "!" in my dialstring, but it didn't work. Are there any solutions? Greetings! Raoul
