Looks like you posted this same question on BroadbandReports.com (http://www.broadbandreports.com/forum/r19418497-Best-settings-for-freepbxasterisk-Calls-randomly-dropping) and someone replied there with a link to a page on the AussieVoIP site that has the settings you should be using (I’m pretty sure that page is also mirrored on this site, but AussieVoIP has better page formatting for most of the articles, and the wiki here is severely broken because no one but the original poster can edit it, which means that bad information can’t be fixed by anyone other than the original poster).
