I'm using converters like these. I've purchased similar converters from 
several e-bay sellers and all seemed to function similarly.

I see no relation but the person having the problem has re-imaged his system several times and when he installs IRLP the messages and courtesy tone goes away. He tells me he has not changed anything else like duplex mode or telem settings.
