We have a group of people who run their own SIP servers

I need to rewrite the identities for the users of our gateway into
something that can be presented to the PSTN gateway for billing
purposes. We don't want to do that mapping on the gateway itself, for
various reasons.
I'm not sure I understand. You want to account calls to PSTN, is that
what you wish to achieve?
- why can't you account to the accounting system from the gateway
-- I think of gateways as a very good place for accounting --
they know everything about a call, including the PSTN side and
media status; they are thus in better shape to account than a proxy is
- what do you mean by rewriting identities? are you thinking of
a proxy which authenticates incoming requests from upstream
and authenticates to downstream gateway as someone else? why?
- what accounting mechanims would you like to use? radius?
Or am I guessing completely wrong and you mean you wish to have
the ability to replace a native sip user name "john.doe" with "his"
phone number 1234, so that the gateway sees "1234" as username and
can propagate it to PSTN?
How do people handle this situation? Is it wise to put
all functionality
for user handling and incoming call handling and forwarding to another
place in the same SER server?
I guess I need to understand better all the things above to answer.
