Re: [OpenSIPStack] Vista Sound Problem

[Whit T. <de...@wh...>]

 I tried using the default value of 5 which works well with Windows XP. 
I had terrible jitter-like audio quality using Vista Premium which led 
me back to the forums to see if anyone else had issues.

I just rebuilt the phone this evening with it set to 10 and so far is 
working well.
