Hi, Here's my setup: (PSTN)--[ASTERISK1]--(IAX)--[ASTERISK2]--(IAX)--[ASTERISK3] I don't run asterisk 1, but I do run asterisk 2 and asterisk 3. I have a DID via PSTN on asterisk 1 that is directed at asterisk 2 via IAX. On asterisk 2 I want to direct that DID at asterisk 3. I have done so, I have the IAX stuff setup between asterisk 2 and asterisk 3, but when I try to call the DID, I get this on asterisk 2: Jun 8 12:50:06 NOTICE[5277]: chan_iax2.c:7183 socket_read: Host [asterisk1_ip] failed to authenticate as [asterisk3_ip] I'm trying to figure out if there is some sort of proxy action that I need to setup somewhere. I can't figure out why asterisk 2 would log a message saying asterisk 1 was trying to authenticate as asterisk 3. #asterisk 2: ; /etc/iax.conf [asterisk3] type=friend username=user secret=pass host=x.x.x.x qualify=yes ; /etc/extensions.conf exten => 4166447887,1,Dial(IAX2/asterisk3) #asterisk 3: ; /etc/iax.conf [asterisk2] type=friend username=user password=pass host=x.x.x.x qualify=yes ; /etc/extensions.conf exten => 4166447887,1,NoOp(Test) exten => 4166447887,2,Answer()
