Steve Z: I have Dummy Repeater speaking to ircddbgateway. Done. Either of 2 ways works: Preferences--> Network--> Local Address = 0.0.0.0 or 192.168.1.10 I've had this working for a while now. It's the part about DummyRepeater --> Asterisk that is not working yet.
My thought it to change the USRP in /etc/asterisk/rpt.conf to 192.168.1.10, and restart asterisk and it would work. There must be more to it.
