Please post a debug-level log of the call.<div><br></div><div>How are you hanging up the call? If with the &#39;hangup&#39; app what parameters do you use?</div><div><br></div><div>In particular if you bridge and it fails with 486 then hangup then the SIP code sent may be from the last bridge cause while the Q.850 cause is the one given to hangup. If that&#39;s the case try setting sip_ignore_remote_cause=true before the bridge and it&#39;ll only send the Q.850-&gt;SIP mapping (<a href="https://tools.ietf.org/html/rfc3398">https://tools.ietf.org/html/rfc3398</a>).</div>

<div><br></div><div>Note there&#39;s no SIP code mapping for 16 though. If hanging up without answering the call use a different cause.</div><div><br></div><div>-Steve</div><div><br></div><div><br><br><div class="gmail_quote">

<div>Hi guys,</div><div><br></div><div>I see that my FS sends sip message &quot;486 Busy Here&quot; with Reason: Q.850; cause=16;text=&quot;NORMAL_CLEARING&quot;.  Why 16 and &quot;NORMAL_CLEARING ? Probably it should be 17 &quot;user busy&quot;. One of my carrier play a &quot;fast busy&quot; (number not available)  and blames Q.850 field. </div>

<div><br></div><div>Any advice are welcome.</div><div>Thanks.</div> 		 	   		  </div></div>
