[Serusers] NatHelper Bug w/fix_nated_sdp("2")

[Maxim Sobolev]

This soft of problems is caused by the fact that you are invoking two 
different SDP rewriting functions in your ser.cfg, such as 
fix_nated_sdp() and force_rtp_proxy(). This is not supported, you can 
only use one of them on the same message and only once.
