B is sending Owner address as

Hi Navneet,
Sip UA(End Point)
behavior on receiving INVITE without max-forwards header depends on
implementation of backward compatibly with RFC 2543.
If the Sip UA(End Point) backward compatible with RFC 2543
then it MUST follow step (d) said by you.
RFC 2543 does mandate Max-

in initial INVITE request among which top "Via header" value has to be selected

Hi,
Can multiple Via header be present in initial INVITE request ?
I mean to say when first time INVITE request is generated from UAC without
traversing any PROXY can contain multiple Via header ?
If yes then what is the need of having multiple Via header in initial INVITE
request?

Hi Jagan,
As per ABNF grammar mentioned in RFC 3261 that Timestamp header can
contain value 0 but no negative value
Timestamp = "Timestamp" HCOLON 1*(DIGIT)[ "." *(DIGIT) ] [ LWS delay ]
delay = *(DIGIT) [ "." *(DIGIT) ]
DIGIT = %x30-39 ;0-9

Caller A has to suffer even knowing at very early stage of
call also he does not have any scope to rectify it.
But If start only after
sending ACK for 200OK of INVITE this scenario can be prevented by sending BYE
for 200OK instead of ACK

not understand that RPR. Server B will be also not able to send Final response
for INVITE as his RPR containing a offer not got any answer. Call cannot be
established.
So server B will discard the INVITE with Require:100rel but no
