I'm not sure I understand. You want to account calls to PSTN, is that what you wish to achieve?
Yes. There are I think 4 entities who all want to share one PSTN gateway. Each will receive a different phone bill, and may want to present different source phone numbers to bill specific groups within their DID.
That said, I'm new to telephone stuff, so I may be asking the wrong questions or using the wrong words.
- 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
For call length, sure, but I need to tell the PSTN gateway the source of the call, and we don't want it to be the one mapping sip:graff@isc.org into a 10-digit phone number.
- 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?
See above.
- what accounting mechanims would you like to use? radius?
that, or sql, or syslog.
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?
Exactly. Only it will see 65077970xx, but that's beside the point.
