If asterisk couldn't decode reliably a DTMF signal on the end of a network link, what makes you think it would survive a analog/digital/analog conversion on top of the lossy codec. If you search the archives, you will find that asterisk will convert the oob DTMF to inband when it goes to PSTN, or at least it is supposed to. I think there may have been some problems lately with the length of a DTMF tone played, but it is supposed to work. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ 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
