[Serusers] Re: [Serdev] Radius accounting unreliable

Guys,

For those relying on Radius accounting generated by SER beware that the combination of RadAcctId-AcctSessionId is not at all unique. If you use MySQL for storage of radius accounting you will miss CDRs every now and then (because is a unique index) and the update queries will update calls from the past as a result, calls with huge duration are being generated.

The problem is generated by a combination of factors:

1. Some UAs reuse same call id among multiple calls (Grandstream systematically show this behaviour)

Indeed, that's why serweb uses combination of callid with from and to-tags for accounting, something similar can be certainly used with Radius+mysql.
