Hi everybody,
Thanks to a contribution from Jeremie, nathelper module offers the possibility to configure the "a=nortpproxy:yes\r\n" string. This is a string marker added by nathelper when rtpproxy is enabled.
The new "nortpproxy_str" parameter: http://www.openser.org/docs/modules/1.2.x/nathelper.html#AEN217
allows you to both change or disable this string marker.

regards, Bogdan
