I completely second that. My original thought was to use ADSI for enhanced caller id information -- like an address or whatever from my own database. But the data/voice context switch takes 5-7 seconds, and it's loud and annoying. Best use would be a one-way setup, where you are simply dialing into your voicemail, checking your bank account, etc. I have yet to get my hands on an IP phone, so I can't compare. > It is too bad.

Yeah, it seems like ADSI was way ahead of its time, but they played it like a monopoly before it was big enough to do so. --Chris -- Chris Maj <cmaj_hat_freedomcorpse_hot_info> Pronunciation Guide: Maj == May Fingerprint: 43D6 799C F6CF F920 6623 DC85 C8A3 CFFE F0DE C146 _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
