[SR-Users] Drop calls with response 200 without previous 180/183 reponses

[Valter Nogueira]

Thank you people. It seems an easy approach using htable.

I was wondering that this is not compliant with RFC 3261, since a proxy
should not change sip responses.

In fact not only I should change the sip response but I should send a BYE
on behalf of the UAC. It seems like a B2BUA
