Found out from the TME: The VG350 performs cable-detection by using low-voltage REN measurement. This means the FXS port will inject a low ring voltage into the line and measure the impedance. If the impedance is low (means there is a ring circuit) the assumption is that there is a phone plugged in.

Hi Rob, I could do that and see if it clears the condition. But I am primarily interested in technically what line condition or test the DSP does to determine connected/not connected. Regards, -John

I have implemented voice-port cable-detect on my VG350 (15.3(2)T) with SM-D-72FXS modules and MGCP signalling loop start. The documentation is not specific as to what is defines "connected" and "not connected" state and I have a functioning phone that shows "not connected" state. How exactly does the DSP detect connected? Thanks, -John

I am interested in determining the differences between distributing sessions via route group/route list vs. single trunk multiple destinations. The assumption is that the destination addresses are identical in reachability and header manipulation. It may be an HA pair or geo-redundant devices. Thanks, -John
