From my experience working with non-secured clusters you need to do one cert at a time to allow CUCM to push out that cert to the phones. Since the phones essentially use 2 certs trust CUCM you can regen them in stages.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><a href="http://www.cisco.com/image/gif/paws/117299/117299-problemsolution-product-00.pdf">http://www.cisco.com/image/gif/paws/117299/117299-problemsolution-product-00.pdf</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>-Erik Anderson</p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:boukilsamadi@gmail.com">Samadi boukil</a><br><b>Sent: </b>Wednesday, June 21, 2017 6:32 PM<br><b>To: </b><a href="mailto:cisco-voip@puck.nether.net">cisco-voip@puck.nether.net</a><br><b>Subject: </b>[cisco-voip] re-genarate certifications</p></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Georgia",serif'>Hi, <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Georgia",serif'>I want to know about the ampact(s) of re-generation of certifications on CUCM 8.x (call manager in Mode secure).<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Georgia",serif'>thanks.<br clear=all><o:p></o:p></span></p></div><p class=MsoNormal><br>-- <o:p></o:p></p><div><div><div><div><div><div><div><div><div><div><p class=MsoNormal><b><span style='font-size:10.0pt'>SAMADI Boukil</span></b></p></div></div></div></div></div></div></div></div></div></div></div><p class=MsoNormal style='margin-left:4.8pt'><b><span style='font-size:7.5pt;font-family:"Georgia",serif'>Élève Ingénieur </span></b><span style='font-size:7.5pt'> <br></span><b><i><span style='font-size:7.5pt;font-family:"Georgia",serif'>Génie Télécommunications & Réseaux<br></span></i></b><b><span style='font-size:7.5pt'><a href="https://www.linkedin.com/in/boukil-samadi" target="_blank"><span style='color:black;text-decoration:none'><img border=0 width=21 height=20 style='width:.2135in;height:.2083in' id="_x0000_i1026" src="https://docs.google.com/uc?export=download&id=0B_xjs74PFblZS01PWV91S01WWXM&revid=0B_xjs74PFblZYkhMeVRWYkdhZ2tIN3lHaG5NK3RMZWIrRlRNPQ" alt="https://docs.google.com/uc?export=download&id=0B_xjs74PFblZS01PWV91S01WWXM&revid=0B_xjs74PFblZYkhMeVRWYkdhZ2tIN3lHaG5NK3RMZWIrRlRNPQ"></span><span style='color:black'>Profile LinkdeIn</span></a></span></b><span style='font-size:7.5pt;color:black'> <br></span><b><span style='font-size:7.5pt;color:black'><img border=0 width=21 height=20 style='width:.2135in;height:.2083in' id="_x0000_i1025" src="https://docs.google.com/uc?export=download&id=0B_xjs74PFblZWU9hNzB0cDQwblE&revid=0B_xjs74PFblZZ1M3b2JBTFp0MjVJL2orUE1OcmZHRStwUE1VPQ" alt="https://docs.google.com/uc?export=download&id=0B_xjs74PFblZWU9hNzB0cDQwblE&revid=0B_xjs74PFblZZ1M3b2JBTFp0MjVJL2orUE1OcmZHRStwUE1VPQ"></span></b><b><span style='font-size:7.5pt;color:black'>+212696184254</span></b></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
