We have a group of people who run their own SIP servers (some are SER, some are not) and we are going to be sharing a PSTN gateway (Cisco box).
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.
