[Serusers] NAT with multiple SERs

Hi all!

We've two SERs balanced via DNS-SRV, and Contacts are replicated via SIP 
between the Registrars. Now I've implemented transparent NAT support, 
but there's a "small" problem :o)

Let's say UAC-1 registers at SER-1, which replicates the contact to SER-2.

Outgoing calls from UAC-1 via SER-1 or SER-2 work great, and so do calls 
from PSTN via SER-1 to UAC-1.

But since there's no NAT-binding for UAC-1 to SER-2, incoming calls from 
SER-2 to UAC-1 can't work.

Does anybody know how to address this issue?

Thanks,
Andy
