[Serusers] Serving multiple domains

Hi List,

We have a few local domains that we will be using SER act as a proxy and to
protect our gateway. In the near future we will also be providing PSTN
breakout for other SIP domains that are not on our proxy.

What is the best way to allow traffic from certain know SIP domains out
through our gateways?
I've thought about having users authenticate to our proxy, but this could
get very complex and messy serving multiple local & remote domains. Other
option is just to allow traffic through from the trusted domains I guess.

One last question, is any one familiar with the Cisco AS5300?
How do you go about locking it down so that only authorised users can pass
calls out onto the PSTN?
We have a number of Vega 100's that have the option of only allow proxy
invited calls. Is there something similar on the AS5300 or would that have
to do authentication aswell, AAA ?

I know that this question is slightly off topic, but with it being related I
thought someone my be able to answer my question.

Many Thanks,
