Hi again, Another "beginner" question : ;-) - I have two duplex repeaters (n° 1 and n° 2), on two separate mountains. Each one has app_rpt configured and running, alone. - I'd like to install a hub (n° 3) in the city, to connect repeaters 1 and 2 - the connection must be permanent : the audio of repeater 1 must be linked permanently to the audio on repeater 2 I read a lot of things, but I do not really understand what to do : - Do my repeaters 1 and 2 have to "register" (in iax.conf) to my hub 3, as ther would register to allstarlink.org ? If so, how should I declare the corersponding "server" in iax.conf on 3 ? - Do I need to declare 3 in the nodes stanza of 1, and 1 in the nodes stanza of 3 ? Or 1 in the nodes standa of 2, and 2 in the nodes stanza of 1 ? - How to make the connection between 1 and 2 (through 3) permanent ? (ie, without having to type DTMF commands to connect) Thank you for this great piece of software ! But I think mastering it will require some time, HI :-) 73 de TK1BI
