<span style="font-family: Arial, Helvetica, Sans-Serif; font-size: 12px"><div>I am having and issue I hope someone can help with..</div>
<div> </div>
<div>I have calls that often come in that need to be blocked. We wish to do this without answering the call.</div>
<div>The issue is our carriers have fail over servers and will try sending the call from each when we block the call.</div>
<div> </div>
<div>If we send a hangup with a Sip 401 they will stop the route advance on their end.</div>
<div> </div>
<div>The issues is we have been sending a hangup/cause code 21 (Call rejected)</div>
<div> But they are receiving a 403 Forbidden..</div>
<div> </div>
<div>Is there any hangup code that we can send that will reply a 401.. We see the 401 on the inbound is converted to a cause code 21 but we do not see any cause codes listed to send a 401 out. Please advise as this a becoming an issue for us as we have multiple vendors expecting a 401 not a 403</div>
<div> </div>
<div>Any assistance is appreciated. </div>
<div> </div>
<div>Thank you.</div>
