Hi

i had confussion with the SIP URI.

  in the RFC 2396, says " This
 ;  "generic URI" syntax consists of a sequence of four main components:

 &nbsp; &nbsp;  <scheme>://<authority&gt;<path&gt;?<query>

&nbsp;  each of which, except <scheme>, may be absent from a particular URI".

here is my question, then the URI Scheme is must be present is it right?. if i am wrong correct me..pls

thanks in advance
