I have a similar problem when my SIP devices dial outside via a Zaptel trunk interface. If I donÂt use "r" my 7960/ATAs/Polycoms work just fine, but Granstream IP Phone and ATA-286 donÂt get ringback tone. I believe the problem is that Grandstream doesnÂt support Session Progress which is a major drawback because when youÂre calling to some cell phone which has voicemail it is usual that you get the voice prompt of the voicemail has a progress tone in order to just bill after the beep which is when the line is answered, with Grandstream if some user calls a cell phone (with voicemail) he/she gets the line answered and just hears silence the problem is that silence is being billed :( -- Juanjo sin .sig _______________________________________________ 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
