Don't know ports. This configuration has been working for about 9 months I purchased a new wireless router to replace a linksys router that didn't have suitable range. Prior to that I have not made any changes since VOIP service started. Problem started about 3 months ago and when I turned everything off and rebooted my computer it seemed to work ok but will not receive any incoming calls at this time. Outgoing calls appear to work.
