Transport Selection and Port Number Determination
Recently I have been experiencing some of the issues while testing IMS which is related to Transport Selection (TCP/UDP selection) or Port Number setting. I haven't got clear understandings of all the details behind these issues that can be stated in this page, but I thought it would be good time to start posting something. This page will be updated frequently and revised/corrected as well as I find more.
