Re: [cisco-voip] Jabber via MRA failover from one CUCM node to another

2020-07-31 Thread Lelio Fulgenzi 
It’s my understanding that although failover doesn’t work, the user can simply 
restart Jabber and then connect to the systems that are up. Is that not right? 
Do they have to wait the 30 – 60 seconds until C/E communicate? Or is it 5 
minutes? I can’t remember the time frame.

They occasionally leak things through there but they’ve been pretty good about 
that lately.

I wanted to test and confirm the MRA failover between UCM nodes but we are 
rebuilding a part of our lab and MRA isn’t running right now.

Maybe later today.

I know for a fact that if you shut down the primary CM in the CMGroup the 
Jabber clients are assigned to, they won’t register. My guess is that this is 
not so much a Jabber limitation but one with the way the registration proxy 
works and how it configures itself for the client based on data it receives. 
The Expressway E doesn’t know about the state of the zones on the C back 
towards the UCM cluster.

But, like we’ve all figured out from trial and many, many errors, these things 
don’t always work in a way that makes sense, and then they’ve been developed 
into a hole that is hard to get out of.

That being said with Jabber’s development pretty much done, are they using 
JabberWerx with Webex Teams or are they spending more time on that code? The 
latter implies that this is why we don’t have multiline there yet, but who 
knows.

Hi All,

I found this old post from Cisco community.
https://community.cisco.com/t5/ip-telephony-and-phones/jabber-softphone-via-mra-does-not-fall-over-to-secondary-cucm/td-p/2807099

Is this still true for Jabber 12.8, MRA 12.5 and CUCM 12.5?

In the MRA 12.6 deployment guide it says
Cisco Jabber clients support IM and Presence Service failover over MRA. 
However, they don't support any other type of MRA-related redundancy or 
failover—including SIP, voicemail, and User Data Services (UDS). Clients use a 
single UDS server only.

In the Jabber 12.8 planning guide, it says High Availability(failover) of audio 
and video service is not supported

If anyone has a MRA lab, can you please help to test it buy just disconnect the 
first cucm node in the jabber's ccm group and verify whether jabber can 
register to the second node in the ccm group?

This is a surprise to me that this fundamental feature is still not supported 
after many years.
