In addition to the potential NAT/firewall issues mentioned by others, I thought that I'd highlight that the Via, Contact, and c= line have different ip-addresses. Such differences are valid; however they are not usually intended.
Via is 10.0.0.2; Contact is 10.100.102.2; c= 85.65.11.138 > I'm expecting to receive audio audio at 85.65.11.138:45000 > but it is not coming.
