Hello Carl,

Thank you for taking the time to provide your insight.

In my experience this system selects incoming calls from the pilot number going up. The outbound calls select the last trunk and hunt towards the first. I am not saying that the system would choose to echo only one direction. Devils advocate speaking up here. What if trunk 2 of 8 had a carrier problem. you would get it on incoming calls frequently and outbound occasionally. If you happened to get the bad trunk #2 and then flashed, you would keep the bad one and the echo associated with that line should remain on it. I am trying to get this test done to verify what I suspect will turn out to be a trunk problem. I came here asking if there could possibly be anything else to look for as I do not know of anything Panasonic that would do this.
