[reSIProcate] Route Set problem with Update in resip 1.1 RC1

Thu Mar 8 12:30:27 CST 2007

Scott,

I may be missing something but....

if (creator && 

(creator->getLastRequest()->header(h_CSeq).sequence() ==
response.header(h_CSeq).sequence())

 && code >=200 && code < 300)

The middle expression will always be true if the lastRequest I send is
CSeq 3 and the response is CSeq 3. Which would also mean that if I sent
an Update (rally any request) and received a 200 OK, I would also update
the routeset.

In other words, that piece is ALWAYS true.... I don't know the
particulars of getLastRequest() so I'm guessing a little.

I have no other private code changes.

	Thanks for trying again Bill - but I must admit - I'm baffled.

	1.       Creator->getLastRequest()->header(h_CSeq).sequence()
should be 1 when initial invite is sent.

	2.       Creator->getLastRequest()->header(h_CSeq).sequence() is
changed to 2 when INVITE with ProxyAuth is sent out

	3.       Creator->getLastRequest()->header(h_CSeq).sequence()
should not be modified again (I can't find any where that would modify
it).

	4.       The 200 response to your re-invite carries a CSeq of 3.
And since 3 doesn't equal
Creator->getLastRequest()->header(h_CSeq).sequence() -> 2 - then the
routeset should not be updated - when using the following code (in
Dialog::dispatch for responses):

	      const SipMessage& response = msg;

	      int code = response.header(h_StatusLine).statusCode();

	      // If this is a 200 response to the initial request, then
store the routeset (if present)

	      BaseCreator* creator = mDialogSet.getCreator();

	      if (creator &&
(creator->getLastRequest()->header(h_CSeq).sequence() ==
response.header(h_CSeq).sequence()) && code >=200 && code < 300)

	      {

	         if (response.exists(h_RecordRoutes))

	         {

	            mRouteSet =
response.header(h_RecordRoutes).reverse();

	         }

	      }

	Any idea's why?  Do you any other local edits that may be
causing creator->getLastRequests sequence number to be incremented
(perhaps modifications to ClientAuthManager)?

	Scott

	Scott, 

	I put your code back in and ran the scenario where I send
INVITE, INVITE w/Proxy-Auth and Re-Invite.

	Each 200 OK updated mRouteSet

	See log snip below:
