This Asterisk (hence off-topic for this forum) warning is to inform you that either:
most likely your NAT setup is failing to route packets to their correct destinations
OR
your SIP client is not responding with an ACK to a packet for which Asterisk believes not receiving an ACK response constitutes a critical failure.
A similar thing has occured previously, and it broke compatibility with an appreciable ratio of common SIP clients.
