Hello all *s, Ok, I have mailed before about a Voice on a POTS Line problem. Well, SJPhone works fine, just installing it allows people on the POTS Line to hear me. So this is not an * problem, but what I have tried (because I am would like to use X-Lite) was to cycle through the codecs that it uses. I have already updated my Windows Client with the .reg file for X-Lite (Bug report: http://bugs.digium.com/bug_view_page.php?bug_id=0000918) for iLBC and SPX. So what I am asking really is how do I determine what codec SJPhone is using to allow Voice on a POTS Line to work while X-Lite can't. -- Kind Regards Etienne
