    FusionPBX call drop problem

    Hello again, Finally it seems that I sorted out the problem. After fiddling with all the True parameters in the internal sip profile, the two settings that did the trick were turning OFF aggressive nat detection and rtp-timeout set to 0. I will keep testing things, but so far so good. Best...
