I will be implementing ip phones on my network shortly, when i plug my clan port into my HP managed switch the connection drops every 10 seconds, but when I plug it into a cheap hub it works fine. Is there a way to set the clan port to half duplex or is there a setting that could fix this problem. I don't want to change the setting on my HP switch because I would like to keep it uniform. BTW this is a IP600 v10. Thanks.
