I was wondering why some of the enum number I was trying were going through PSTN... In the cli output, only e164.org was checked... Looking in /etc/enum.conf I had however the full list of e164.org e164.arpa e164.info enum.org then i looked in /var/lib/asterisk/agi-bin/enumlookup.agi and I found that the enum site were coded in hard in the agi, and all were commented out excepted the first one... To restore all of them, just comment them out. http://www.freepbx.org/trac/ticket/3423 Also you can also experiment with this reworked agi http://pbxinaflash.com/forum/showpost.p ... stcount=22 this agi is supposed to read the enum.conf file. It also added some options to prohibit some specific gateway (like some well known unreliable 1800 US gateway).
