Ok... Maybe you&#39;re right. I&#39;ve read somewhere that this service is needed for taping reasons (policy and other law enforcements). If it&#39;s needed whe can just turn it on for that specific number, right?<br><br>But answering to my question, can you point me some ideas refering about equipment that i should use?<br>

Yes. &nbsp;There are some liabilities with that in that the signaling messages may be incomplete (i.e. you may miss a BYE) and this is the usual reason given for doing media proxying for more accurate accounting.<br>
<br>
But the latency, bandwidth consumption, and increased complexity and cost associated with doing it on a large scale does not justify it, in my opinion. &nbsp;SIP-only accounting is &quot;good enough&quot; most of the time.<br>

Without mediaproxy? Only based on SIP messages?<br>

 &nbsp; &nbsp;You can do accounting without handling media.<br>
