Linksys SPA3102 Modified Configuration- Incoming Calls

Here are the settings for the Linksys SPA3102 that allow us to call the local 913 number assigned to the device and have it forward to an XLite softphone. You need to log into the Linksys and switch to admin mode, "advanced" configuration.

**Also note that this is the result of several contradicting directions, found here, here, and here.

These are the options I changed. If something isn't mentioned, the default setting should work.
