Hello all. New user here trying to get up to speed. I connected a DMK URI to our Asterisk running ACID. We configured it as follows: ----------usbradio.conf------------- [general] [usb] hdwtype=0 rxboost=1 rxctcssrelax=1 rxctcssfreqs=100.0 carrierfrom=usb ctcssfrom=usb rxdemod=flat txprelim=yes txlimonly=yes txtoctype=notone txmixa=voice txmixb=no invertptt=0 duplex=1 ------------------rpt.conf-------------- [1444] rxchannel=Radio/usb erxgain=-3 etxgain=3 controlstates=controlstates functions=functions phone_functions=functions link_functions=functions telemetry=telemetry wait_times=wait-times context=radio-usb callerid="WB2ERS" <0000000000> idrecording = |WB2ERS accountcode=RADIO hangtime=1000 althangtime=4000 totime=170000 idtime=540000 politeid=30000 idtalkover=|iid nounkeyct=1 duplex=1 ----------extensions.conf---------- [radio-usb] exten => 1444,1,Ringing exten => 1444,n,Wait(3) exten => 1444,n,Answer exten => 1444,n,Rpt(1444|X) exten => 1444,n,Hangup -------------iax.conf-------------- [IAXURI] type=user context=radio-usb auth=md5 secret=mysecret host=dynamic disallow=all allow=gsm notransfer=yes callerid=IAXURI We have one way audio and signaling from the Ethernet side to the radio side however from the radio to the Asterisk, nothing. I verified that CTCSS detect (pin 7) goes from 5v to 0v upon receive signal . I have the receiver audio connected to pin 22 Left_Out. Any ideas? Mark DuMoulin WB2ERS Wb2ers@metcom.com C 800-410-3130
