Second BYE I dont get, so thats all good, as for the rejection, the UA
seems to reject it, i.e I dont get a second call etc, but SER still
account for it, should ser also reject

According to RFC3261 the second INVITE (with a
different branch value) for the
same (early) dialog should be rejected with 482 Loop Detected. So if you are
dealing with good UA's it should be no problem. Otherwise the UA is broken.
The second BYE should not appear, as the BYE should be routed according to
routing informations within the BYE, and thus not be duplicated because of
several ursloc entries. If the INVITE and BYE gets duplicated because of
something else then usrloc, you should prevent the duplication for all
in-dialog requests (e.g. re-INVITE's too).

Hi
I am getting 2 INVITE per call, which is correct in my setup.
I have IP phone ---> ser---> asterisk----ser----ip phone for various setups
So when ip phone makes a call, to a internal extension, the call goes
out via ser (INVITE 1) into asterisk, which then maps this internal
extension to a external number and hence issues a DIAL sip/xxx statement
(INVITE 2). All well and good
Now should this not give two BYE's anyhow it gives one.
The other thing is what to do with the two INVITES, should I be taking
the INVITE from asterisk, or from SER, I think the former, BUT the BYE
seems to match the tag for asterisk INVITE
