[Serusers] OPTIONS method

[Nils Ohlmeier]

Hi Greg,

OPTIONS is a request which determines the capabilities of the destination. A 
UA or a proxy should answer with its supported features (see RFC for 
details).
I think Ser is currently not able to answer such a request correctly. But i 
have never seen a UA which queried the server. You can send an OPTIONS 
whenever you want, for example to change the connection with a re-INVITE, 
allthough it makes more sence to query the capabilities before a connection.

But OPTIONS is also used for "traceroute" (see RFC for details, and sipsak for 
an implementation) because it do not establish a call to the UA.

Regards
  Nils
