[Serusers] Parse Error : Bad Via?

[samuel]

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
