[App_rpt-users] IRLP Disconnects and Audio problems

I am having trouble with Allstar not having any audio coming back and out going is very weak. Is there a echo type server to test ones audio? The IRLP side works fine. Also, when someone connects on IRLP it disconnects them. I can connect somewhere and it will stay linked. Are there some parameters that I missed for both problems in one of the .conf files? Thanks, Greg
