Comment #9 on issue 2354 by jean.deruelle:
B2buaHelper.createResponseToOriginalRequest() does not set different To tag
to created response.

This issue was updated by revision r17838.
Fix + non regression test.
We allow to forward provisional responses (to play mandatory early media by
example) and create derived session for it. But forwarding 200 OK is not
allowed as per RFC3261 and TCK test
com.bea.sipservlet.tck.agents.api.javax_servlet_sip.B2buaHelperTest.testCreateResponseToOriginalRequest101.
The decision has to be made at the B2BUAHelper when a 200 OK has already
been forwarded and the B2BUAHelper should CANCEL other branches upon
receiving a 200 OK. If there is a race condition and another endpoint sent
a 200 OK before we had the time to cancel the leg then it should be ACK-ed
and BYE-ed
