Hi,
If your proxy parallel-forks to both registrars, and one registrar replies with a negative final reply (like 408), that’s no problem. You still have branch #2 to the other registrar, and if that generates positive replies, it is those “winning “replies which will be relayed back to the caller, not the ones on the “losing” branch(es).

Hi Alex
Thank you for your input. Determining if the call is for a locally registered user seems pretty easy.
Now the next challenge...
There might be multiple registered contacts for an AOR using multiple protocols and residing on different registrars.
I was considering using dispatcher mode 12 (parallel branching) towards the registrars and just send a call to both our registrars node.
But what happens, if there is only one contact registered, obviously on one registrar? The call sent to the 'wrong' registrar would get a reply like 408 not registered and possibly trigger the failure route to voicemail, while the other registrar is routing the call to the CPE?
Is there a solution for this scenario, or do I have to get rid of having two registrars for redundancy and HA reasons and would better do with only one node?
Mit freundlichen Grüssen
