I've been thinking about this for awhile and have yet to try the method used in these instructions that were suggested by another forum member:
http://gurnted.wordpress.com/guides/ I triedthe instructions she suggested in her posts, but found it very confusing. Is anyone willing to try this out and set up a nice tutorial on the forum or confirm that the instructions in that blog work (and which one of the two works)? I assue you that many people would appreciate it (I mean c'mon FREE VOIP on the edges).
