Re: [Serusers] CDR Issues

For the scenario we are talking here about, you can not guarantee 100% accurate accounting except you are using a B2BUA. Because if the call is on hold it could stay in that state forever. If the UA's do not support RTCP you will not see any traffic from them if they are restarted or cut off from the net. So IMHO the only way would be to probe the UA's regularly with SIP requests which check if the dialog between those two parties is still alive. And if you want to support all possible UA's this SIP request would have to be an re-INVITE. If you then get an 408 or 481 from one partie you can safely create the "call end" record. So at the end you need a B2BUA.
