Hi ,
can you double check that you do actually save the BYE request ? I
couldn´t see the code in the doBye method.
protected void doBye(SipServletRequest req) throws
ServletException,
IOException {
SipSession downstreamLeg =
(SipSession)req.getSession().getApplicationSession().getAttribute
("downstreamLeg");
SipServletRequest byeRequest =
downstreamLeg.createRequest("BYE");
// Copy the content from the downstream response to the
upstream
response
if (req.getContentType() != null) {
byeRequest.setContent(req.getRawContent(),
req.getContentType());
}
byeRequest.send();
}
Anyway.... when doing B2BUA you tipically don't need to wait for
200OK to generate BYE response. You can simply send a 200OK to any
incoming BYE request (since there is no SDP involved in the BYE
handshake) then finish the other leg. The idea would be doing
something like this (not 100% real code, some pseudocode here)
protected void doBye(SipServletRequest req) throws
ServletException,IOException{
//Answer positively
request.createResponse(200,"Have a nice day").send();
//Mark my dialog as finished
request.getSession().setAttribute("FINISHED","OK");
//Get the other leg and finish it in case it is not finished
//Note how useful is to have in both SipSessions (that is, both
legs) an attribute which refers the
//other leg involved in the B2BUA transaction.
SipSession counterPartLeg= (SipSession)
request.getSession.getAttribute("COUNTERPART_LEG");
if (counterPartLeg.getAttribute("FINISHED")==null){
counterPartLeg.createRequest("BYE").send();
}
}

Hi Gines!
It's almost clear to me how to do, this what i have done and it works.
now i need last clarification how forward the 200 OK from BYE
request, i
cannot get it working.
for forwarding the 200 ok from the BYE in the doBye request i save
downstreamLeg.setAttribute("byereq", req) and then in the doResponse i
get the bye request and create the response from it,
something like this but i'm wrong.
if (resp.getStatus() == 200 && resp.getMethod().equalsIgnoreCase
("BYE"))
{
SipServletRequest upstreamRequest =
(SipServletRequest)upstreamLeg.getAttribute("byereq");
SipServletResponse upstreamResponse =
upstreamRequest.createResponse(resp.getStatus(),resp.getReasonPhrase
());
//Copy the content from the downstream
response
to the upstream response
if (resp.getContentType() != null) {
upstreamResponse.setContent(resp.getRawContent(),
resp.getContentType());
}
upstreamResponse.send();
}
this is what i have done for working ACK.
protected void doAck(SipServletRequest req) throws ServletException,
IOException {
//Retrieve the upstream request to respond it
SipSession downstreamLeg =
(SipSession)req.getSession().getApplicationSession().getAttribute
("downstreamLeg");
SipServletResponse downstreamResponse = (SipServletResponse)
downstreamLeg.getAttribute("200ok");
SipServletRequest ackRequest = downstreamResponse.createAck();
//Copy the content from the downstream response to the
upstream
response
if (req.getContentType() != null) {
ackRequest.setContent(req.getRawContent(),
req.getContentType());
}
ackRequest.send();
}
protected void doBye(SipServletRequest req) throws
ServletException,
IOException {
SipSession downstreamLeg =
(SipSession)req.getSession().getApplicationSession().getAttribute
("downstreamLeg");
SipServletRequest byeRequest =
downstreamLeg.createRequest("BYE");
// Copy the content from the downstream response to the
upstream
response
if (req.getContentType() != null) {
byeRequest.setContent(req.getRawContent(),
req.getContentType());
}
byeRequest.send();
}
protected void doResponse(SipServletResponse resp) throws
ServletException, IOException {
if (resp.getStatus() == 200 &&
resp.getMethod().equalsIgnoreCase("INVITE")) {
SipSession downstreamLeg = (SipSession)
resp.getSession().getApplicationSession().getAttribute
("downstreamLeg");
downstreamLeg.setAttribute("200ok",resp);
}
//Retrieve the upstream request to respond it
SipSession upstreamLeg =
(SipSession)resp.getSession().getApplicationSession().getAttribute
("upstreamLeg");
}

The problem is that you didn't implement the
doACK method. Implement
it following a similar technique as the one used in doResponse. Save
the 200OK response in the downstream session so you can retrieve it
when the ACK arrives from the upstream then generate ACK using
response.createACK() and copy the content using getContentType/
setContentType geContent/setContent if required
Hope it helps
