And the B2BUA would have to keep database of user passwords very
much the same way the registrar does. This data redundancy makes
me think that such a netowrk is actually quite suboptimal -- why
can't be the registrar in the same box as proxy/nat?

Hello,
no, it is not possible because you can't change To and From header
fields in the message and also the gateway ser can't respond to digest
challenge from the registrar because it doesn't know user's credentials.
You will need a B2BUA for this kind of job.

Hello All,
Can anyone tell me whether the following setup can be achieved with SER?
[UA] <-------> [Gateway/NAT/SER Proxy] <--------> [SER Registrar]
1. The UA is behind a NAT gateway.
2. Whenever the SER Proxy on the NAT Gateway receives a registration request from a UA (
tester@gateway )on the private network, it sends a registration request (
tester@ser-registrar ) to the "SER Registrar" on behalf of the UA. This means
the SER Proxy should be able to translate a SIP URI on the public side (
tester@ser-registrar ) to one on the private side ( tester@gateway ) and forward it to the
right machine.
Any feedback will be greatly appreciated.
Regards,
