[Serusers] Audio Problems on SER !!!

Hi everybody, I'm experiencing some problems with the audio of my server. My SER is configured with mysql auth and was working very well the whole friday, there were 6 people talking to each other within our private network, but today, I can't make a decent call, because the noise is very loud at every soft or hard phone I try internally. What May be that ?? Is there documented some codec audio problem about that ? Could it be a problem in my network ? Another question, I have ser worknig at a private network, with his Default Route to one of my internet gateway, My tests machine are connected via a hub just for tests, and this hub to my private network, which leaves to the internet. When I test it internallty there no problem occurs, but when I swich off the eth cable that leads to the internet (I mean the one that is my default route) SER stop authenticating my users, and I can't make a internal call. Is this a bug ??
