Hi, I have been looking for up to date configuration documentation for IIS 7 and 3CX, but cannot find it. There is an IIS troubleshooting blog post, but: a) 3CX on IIS 7 "seems" to work fine with a default configuration. But does it need some customization to be optimal? b) the IIS troubleshooting blog post is mostly to do with IVR, and it's not clear to me whether these are standard configurations that should be made on all 3cx/IIS installations, or, only when there is "trouble". c) the links to MS KB articles by the blog post are quite old, for IIS v5 and 6. A lot has changed in the MMC, and most folks are going to have a hard time locating the features that need customization. That is me included. So - does IIS need customization beyond what 3cx install does? If so, what are they? If this information is already published, please point me to it!. If not, a how-to would be great. Thanks, Les.
