Good day!<p>We have next task. We need config SIP trunk between FreeSWITCH and CUCM 7.1. FreeSWITCH have to register on CUCM.</p><p>We have made in CUCM SIP trunk with correct <a rel="nofollow">SIP Trunk Security Profile</a> for authorization and created Application User.</p>

<p>But FreeSWITCH can not registered. There is 405 error &quot;SIP trunk disallow REGISTER&quot;. See attachments.<br></p><p style="min-height:8pt;min-height:8pt;padding:0px">Maybe someone faced with a similar problem?</p>
