I've followed some suggestions and got to check sip packets and got this. Change some configs, but couldn't get any NAT configuration to work, hoping to get a new opinion if it still, maybe it is a problem with NAT or maybe another thing. #-------------------------------------------------------------------------------------------------------# #-------------------------------------------------------------------------------------------------------# Called from "outside" and my microsip doesn't have STUN Server on.
