The Via header ends with a semicolon (;) and that's not a valid end of header character. I've seen this problem when there's a SIP ALG in between the UA and SER that removes parameters but does not do it properly. The problem I faced was with rport parameter: the UA added rport to Via header, the router removed the rport BUT it left the semicolon->invalid header!!!! 

Solutions:

1.- Stop SIP ALG in the router!!!!!!->It will save you further headaches and weird behaviours....
2.- Configure UA to not use rport parameter.

Hope it helps,
Samuel
