<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">8811 shipped with 10.3.1.-20 firmware, CUCM 12 and CUCM 10.5 both have default load for 8811 phones set to 12-1-1SR1-4.<o:p></o:p></span></p>
<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">

<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">Customer acquired some new 8811 phones with super old firmware. Unboxed them and attached to the network where other IP phones (8851,8861) are up and registered to CUCM 12.0.1.22900-11. The 8811 would
not upgrade code. It had an error in the phone log about the default xml config file. Tried resetting security settings, full factory reset, etc.. Nothing worked. I was suspecting the old "2-hop upgrade" might be needed, but that didn’t work either.<o:p></o:p></span></p>

<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">I then erased the phone again and connected it to a CUCM 10.5.2 SU2 system with the latest device pack. The default phone load on this CUCM 10.5 was the same as CUCM 12.0 and the 8811 phone was still
at firmware 10.3.1-20. The phone upgraded code no problem.<o:p></o:p></span></p>

<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">Once the phone was on firmware 12.1.1SR1-4, it registered fine to CUCM 12.0.<o:p></o:p></span></p>

<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">My current working theory is that CUCM 12 seems to use an EC certificate on the HTTPS service that newer phones use to download firmware (
<a href="https://%3ccucm%3e:6972">https://<cucm>:6972</a>) , and the old firmware doesn’t support it. But if this was true, why didn’t the 8811 phone fall back to plain-old TFTP over UDP 69.<o:p></o:p></span></p>

<p class="gmail-msonormal" style="margin:0cm;margin-bottom:.0001pt;line-height:105%">
<span style="font-family:"Arial",sans-serif;color:black">The big issue is that I have 100's more of these 8811 phones in boxes and having to unbox each of them and temporally connecting to a CUCM 10.5 to get firmware upgraded is not a task I'm looking forward
to.<o:p></o:p></span></p>
