Installed New CIX40 with current 061 release. Assigned extensions to All Page and put RCA cable in ext spkr port. Connected to Bogen TPU15 on tip and ring. Pages phones great nothing over Horn. Put Tone generator on RCA plug and warbles over amp and too the speaker fine. Tried this on another new CIX40 connected same way. Same Results. Am I missing something here on these Ver 3 processors?? Also, checked ext port with butt set and nothing coming out. Thank you.
