[Serusers] rtpproxy problem

[Jan Janak]

Make sure that you do not rewrite the IP address in SDP twice, that
means if you call force_rtp_proxy then do not call fix_nated_sdp and
vice versa. Both of them try to rewrite the same IP address which is
incorrect.

The errors below mean that you try to call nathelper functions on a
function with empty message body (probably ACK, BYE, or CANCEL).
