thanks for u reply and i cant uderstood the second sentence i.e underlined part.Can give more information about that



 
For media transmissions SIP uses only udp 
right??
tcp media is not supported.
 
And we can use TCP/UDP both. but it depends on users how it 
will reply for TCP/UDP via header fields.
 
Thanks,

 *when a sip 
      enabled end device opens a TCP connection and when it uses UDP to send 
      *REQ/RESPONSES to proxy or other UA.
*can it use both in a  
      aparticular diloge i.e to send INVITE use TCP and to send ACK 
      use       
  UDP.
*Can we force 
      it to use TCP/UDP.
*For media transmission SIP uses only tcp.Is this 
      true.
