[cisco-voip] CUCM SU release cycle

Thu Aug 15 13:57:25 EDT 2019

I’m hoping that Webex calling will come out with a “video mesh node” equivalent, so when your WAN link goes down, you have nodes on-premise to service your phones.

That being said, chances are, that won’t happen. Cisco is going to expect you to have a “Cloud Ready” network with multiple paths, QoS and peering set up.

I’m guessing may providers will soon have a backup 5G/6G cellular data option available so if that squirrel finally gets through chewing the fibre, you can prioritize voice traffic over the wireless backup link.

Cloud is good for some things, IMHO, but not a once size fit all.  As we saw from last year, the cloud is not immune to outages.  Unless you are big enough to get a dedicated circuit, you have QoS issues.

I have yet to see WxTeams work seamlessly on my mobile, the bug is back where it continues to ring after I answer on elsewhere.

My cloud connected home phone is rock solid (8865 to WxTeams), aside from the occasional QoS hiccup, but I would get that with any provider, not just Webex.

Would I advise my bigger customers to switch?  Not yet.  Hybrid calling is good for now and a properly built UCM cluster just can't be beat if you have a well built network, etc.

Cisco is paying for clients who get “Cloud or Bust” tattoos.

That’s a sign of good things to come.

I’m convinced.

Let’s not get ahead of ourselves there ;). Just like war, usually (but not always) the people who want 100% cloud calling or think it’s a great idea are the people who’ve never experienced it.. lol

You forgot how everyone will be migrating to Webex Calling before then. And your upgrade cycle will be out of control. Just like how Webex Teams has that green restart symbol every two weeks.

So if I do the math...

No more minor versions
...punches some keys...

And 2 month SU cycles
...punches more keys....

With an upper limit of 3 SUs
...punches even more keys...

That's a new major version every 6 months!

That means we'll see
..key punching intensifies...

CUCM 69 by mid-2046.  Just in time for me to retire!

Pretty sure I remember them saying there likely wouldn’t be that many SU’s either, three at most?

*sigh*

Make it SU5 in memory of the .5 releases.

I didn't see an announcement, was just told about the change, Cisco doesn't like us waiting for the .5 release to push out to customers.  We all know that the .0 releases have historically been more challenging.

So now, I plan to wait until at least su2 before upgrading :)

Why not just all Major versions all the time?  Google Chrome is on version 76.

But seriously though, anyone got a reference to this announcement?  I didn't see it in the cisco live preso linked earlier.

If not, what's the reported reason for dropping minor release numbers?

After 12.5, no more “.5” releases, it’ll just be major versions (and the SUs in between). After 12.5 we skip 13 and go right to 14 (then presumably, 15 after that).

What's going on with .5 releases?  I don't think I heard about that.

Yeah, I think with the move away from the .5 releases, we'll be getting more SU's and less major releases.

Hi Group,
in the past , the SU release is every 6 months (usually longer than that, approximately twice a year maximum) but now Cisco is changing to every 2 months?
