Don't the Grandstreams send a DTMF 'F' INFO message on a hookflash? Shouldn't be that hard to change chan_sip to register an 'F' as an AST_FLASH control message. I'd do it, but I couldn't test it...since it seems that Grandstream hasn't found it in the goodness of their heart to add hookflash support to the HandyTone ATA. _______________________________________________ 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
