<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">You can add a 2<sup>nd</sup> cert to the VPN Gateway configuration after you add it as a VPN-Trust.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">So what you want to do is create a new trustpoint on the ASA with the new certificate, upload that to CUCM as a phone-vpn-trust, and then add it as a 2<sup>nd</sup>
cert to the VPN Gateway.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">You’ll then want to make sure all the VPN phones get reset so they get the new certificate as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">After all the VPN phones have both certificates, you can then change SSL on the ASA to bind to the other trustpoint and start using the new certificate.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you follow that method, you want have to bring any of the VPN phones back in as long as they’re connected. The main problem with this method is some people
have VPN phones that they rarely connect so you’ll need to make sure everyone connects their phones to get the new certificate before you make the change on the ASA.<o:p></o:p></span></p>
