Re: [Serusers] Feature Request: Log Contact hf of 3xx Response in Accounting

When 3xx comes back to caller it should accept or reject the redirection, so it should be charged for the call, not the callee. One problem is that the new call will have different dialog characteristics (callid, tags ...) and you do not know if the call is really due to 3xx or because the caller had dialed by itself. There are phones that do not handle redirection at all and the caller may have the PSTN number of callee as well which may be the same number from 3xx contact. Another problem is that SIP phones/clients usually do not ask to follow or drop a redirection, so a better approach would be to drop 3xx replies on server and implement call forwarding on server where you can log more details about the call and you are sure that callee must pay.
