[OpenSER-Users] How do I detect INVITE loop

Hi, Is there a way for an OpenSER instance to detect if an incoming INVITE message has earlier been processed by itself? Record-Route is on, so there should be a Route message, but I suppose the Via headers could also contain the information. If it is detected I'd want OpenSER to ignore the incoming message, I suppose I could do nothing (no lookups etc.), but is there a better way? This is an issue because of the way we handle UA's registering at instance A and UA's registered at instance B wanting to call UA's at A. Due to race conditions with registrations going from A to B there are possible looping scenario's. -- Andreas Sikkema
