Quick little update on this issue since there were so many helpful
suggestions when I started troubleshooting this.
After a good bit of education and 'engineering' on my part I was able to
load the backups from the night before the upgrade and the night after the
upgrade onto VM's and get a look at the particular device configs before and
after. Nothing looks out of place to me, which is leading me to think there
was some issue with either TFTP, or some communications with the CM nodes
and/or devices which would cause side cars and phones to not register or
recieve phone calls.. unfortunately not something I can really troubleshoot
so well from the lab. The issues with lines disappearing out of the CM
configs seems to me to be human error.. the techs thought some things were
supposed to be there that never were.. helpful (><)
TAC is looking at the logs I collected from the event, i'm getting ready to
update the SR with my own findings from the lab work once I get feedback
from the folks on-call that took the problem reports.
I'll update the list again if anything interesting pops up from this.
