In trixbox (asterisk 1.2) I had setup ring group with distinctive tone ringing using alert_info option (e.g. bellcore-r2). This does not work in elastix 0.8.4-beta2. I read further and found out that Asterisk 1.4 treats alert info in a different manner. Please take a look at distinctive ring styles section at http://www.voip-info.org/tiki-index.php?page=Asterisk SIP Channels Is this modification done in freepbx? If yes, I cannot get it to work, anything else that I need to be aware of? The above configuration was working fine with trixbox 2.X/asterisk 1.2. I am using unlocked PAP2 to test and it does support distinctive ringing. Thanks, BTW Great product, I personally wanted postfix as MTA, you got it out of the box.
