The signalling is not correct but, I have looked your code and believe that it is right, revise it and you check if you have the last version of WeSIP and you return to try, because the last release commited in HYPERLINK "http://www.wesip.com/mediawiki/index.php/Downloads:WeSIP_Beta_0.1%22http://w... w.wesip.com/mediawiki/index.php/Downloads:WeSIP_Beta_0.1 was fixed a bug with the ApplicationSessions.
In my test application I reply your behaviour(with 5xx, with AppSession attributes) and all have working perfectly, I dont understand nothing :(
Sorry
Good Luck.
Antonio

Hola Antonio,
Your example works great and the code is more clear and correct than
mine :)
i was not clear, my problem was only with the 503 Service Unavailable
response, that means a 5xx Server Failure, is it possibile that when the
container or openser with seas recive a 5xx response is not able to do
for example a creation of a new invite to UA3 recover from the same
session?. Or probably i'm occur in a 473 response for an incorrect use
of SipApplicationSession.
anyway with a 480 Temporarily Unavailable response from the UA2 i solve
my problem.
thank you very much

Hola tele ;)
I have tested an example similar to yours, and it works ok. It's de
following:
UA1 ---[1]--> WeSIP --[2]--486 Busy Here---> UA2
|
[3]
---OK----_> UA3
[1] UA1 generates an INVITE to UA2 ant it 's forwarded to UA2 with a B2BUA
behaviour. In do INVITE. I have implemented the following:
protected void doInvite(SipServletRequest invite){
SipServletRequest otherInvite = sf.createRequest(invite, false);
SipURI sipUri = sf.createSipURI("UA2","proxy");
otherInvite.setRequestURI(sipUri);
otherInvite.getSession().setAttribute("REQUEST", otherInvite);
otherInvite.getSession().setAttribute("PEER_SESSION",invite.getSession());
invite.getSession().setAttribute("PEER_SESSION",otherInvite.getSession());
invite.getSession().setAttribute("REQUEST", invite);
otherInvite.send();
}
[2] UA2 declines the call and a 486 response is received by WeSIP and
process it in doErrorResponse:
protected void doErrorResponse(SipServletResponse errorResponse) {
switch(errorResponse.getStatus()){
case 486:
SipServletRequest request = (SipServletRequest)
errorResponse.getSession().getAttribute("REQUEST");
SipSession otherSession = (SipSession)
errorResponse.getSession().getAttribute("PEER_SESSION");
SipURI sipUri = sf.createSipURI("UA3", "proxy");
request.setRequestURI(sipUri);
SipServletRequest newRequest =
sf.createRequest(request,false);
newRequest.getSession().setAttribute("REQUEST", newRequest);
newRequest.getSession().setAttribute("PEER_SESSION",
otherSession);
otherSession.setAttribute("PEER_SESSION",
newRequest.getSession());
newRequest.setHeader("X-SSVTPBX", "yes");
newRequest.send();
break;
}
}
[3] UA3 Recevies the second call and it takes down.
I do not understand the cause of error. I annex you the code of simple sip
application example that replies to your problem. You can start it up and
checking if it works. Else if work for you, I would attempt watching the
particular case when a 5XX responses are received.
Sorry...
Best regards.
Antonio.

Asunto: RE: [Users] WeSIP session question
Hola Antonio,
The scenario is more complex, i'll try to explain it:
PSTN
|
|
UA---->GW ------> WeSIP(B2BUA)
|
|
mediaserver
GW: 82.215.163.5
WeSIP: 82.215.163.67
MS: 82.215.133.50
in the mediaserver there is an vxml script that i play in early media
and in case of particular event return to wesip a 503 temporaly
unavailable or e 410 Gone. So my B2BUA application have control of this
and can do stuff with the 503 and 410.
in particular, in case of 503 temporaly unavailable i get the upstream
session and create a new invite to the media server for play another
announcement associated. in case of 410 gone i generate a new invite to
the GW with the original URI request for the correct termination.
Yes when the session is removed i'm able to send another call.
attached here the logs and the servlet.
don't care about the hardcoded IP and the repeated code :-)
i'm doing testing..
regards,
:tele

Hi Tele,
I don't understand very well the problem., for what I understand you
have
the following:
UA1 --------------------- WeSIP --------------------- UA2
---INV/4XX-6XX/ACK (SS1) --> ----INV/4XX-6XX/ACK(SS2)-->
You try to send another call and receive the 473 response of WeSIP...
------INV/473/ACK (SS1) -->
And when the session has been removed you can send another call.
If it is the case, I understand that the 473 response is send from
application or from openser script configuration, because the internal
behaviour of SIP doesn't send this response automatically.
Can you verify if it is the case?
Thank you very much...
Antonio.

I've read the sip servlet spec about that and i'm trying to invalidate()
or setExpires() to SiApplicationSession in case of failed call. but it's
not clear how to do yet.
i can provide the full debug if needed.
thank you!
