Hi ,   I have a  doubt in handling "via and contact" header fields,    AS per the RFC  
3261,  "Via header field tells other elements where to send the
   response and  the Contact header field tells  other elements where to send  future 
requests."   If a softphone A sends a INVITE message  with a "via header field 
containing the IP adress of   some other softphone say B ,  then  the response for 
this INVITE  will be sent to B or not ?.   ----

No, there is a misunderstanding. Only A is able to stamp its address in the via header 
or a proxy where the message is forwarded to. The response of B will use the last via 
header and send back to this address. If this address is a proxy, the proxy will 
remove its address and send to next via header until a will reach.

A will also set the contact header with its contact ([EMAIL PROTECTED] or [EMAIL 
PROTECTED])
