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.
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?
