[Users] REGISTER expires and replication

Hi, I have a scenario in which I have a little bit of confusion..

I have a redundant setup, two OpenSER, a MySQL cluster and replication of REGISTERs.

The UAC sends expires=3600 Both OpenSER's has a max_expires=1800, min_expires=300,default_expires=300

My Sipura-1001 has default expires=3600.

In the OK message sent from the OpenSER handeling the REGISTER, expires=1800 is sent back to the UAC which is OK (However the Sipura does not obey this, which also is struggeling, but that is another story....)

The replicated REGISTER, hovever, uses the original expiery from the UAC...expires=3600

Do I have to rewrite the expires in the replicated message?
