I am looking for Call-flows for SIP-RTP-Meida Loopback, can somebody point
me ink on this?
Thanks in advance,

Busy here would give a wrong impression, caller would try repeatedly, better
include some retry-after header.

It is perfectly valid, there are lots of such scenarios, simplest example is
call-hold.
Session refresh is one more scenario. Please go through RFC3261.

Hi Attila,
I wonder if the following topology is invalid, in which case the forwarding
stateless proxy
can as well put the received information in Via header.
If UAS erases the received information then it would be impossible for the
proxy would send response to UAC.
UAC NAT1
Note that the Content-Length header is not mandatory in SIP on UDP. If body
is there then content-type header will be there in all positive cases. You
need to interpret
body based on the content-type header.

. Will the continuing call
cause a mismatch of the stream?
Please also give reference about this beahvior? Thanks,

As such for compatibility reasons nothing can be inferred from to-tag
in 100 Trying.
That is, there won't be any use even if it identified that the dialog
has been established.
If you are thinking on how to terminate the call at this point then
CANCEL still holds good.

Ignore 180 with 'NO SDP', better give preference to 18X with SDP.
in some cases you may receive 180(SDP) then 183 (SDP) (very rare
cases) but I have seen such case, in such cases generally 180 (SDP)
will be inband ringback and 183 (SDP)
may be inband ringback or an announcement so better switch
