#192 Consistently use rtpproxy switches

[Peter Lemenkov]

The flag for marking party as being behind the symmetric proxy is 'S', not 'W' as it was implemented in nathelper. Moreover 'W' has also different meaning in rtpproxy protocol syntax.

Unfortunately this is obviously an incompatible change, however I think that elimination one source of confusing worth applying this,

Hi Peter,

Thank you for your patch. As you might know, the 'S' flag was used in the nathelper module to swap between session creation and confirmation. This flag became later deprecated, when rtpproxy_offer and rtpproxy_answer functions were introduced.
We haven't changed the 'W' flag into 'S' yet for backward compatibility, but we are considering it in the future.

Thanks again and regards,
Răzvan Crainea

Hello, Peter!

I have just added the 's' among the flags that can be passed to rtpproxy. Also, 'w' can still be used for backwards compatibility.
Thank you for the patch!

Răzvan
