Hi all,after a long and happy experience with sofia, I've just noticed that I'm not able to properly answer INVITE requests with NTA. In fact, when the tranport is UDP, the 200 response is sent back only once, even if no ACK is received. I'm sure it's my fault; I've attached a short program to reproduce the issue. Can anyone please tell me what's wrong with it?
