Here's the layout:A bunch of locations in Webex Calling. Each location will also have an on-prem CUBE (LGW) that will be used for connectivity to that site's overhead paging system. I would like each site's paging process to use the same dial patter...

I have a situation where a customer has a large number of ATA191s in their environment. They are all in voice subnets where the desk phones on those subnets are being tracked correctly by CER but none of the ATAs show up in the subnet. I thought th...

I created a Webex Calling Sandbox about a year and a half ago while running through some training and everything worked great. I need to use it again, but when I log in it says there are no licenses associated with it. I can't figure out how to get...

So 2 updates and a year later and Cisco still hasn't gotten around to fixing the problem.Telling a customer that they have to spin up a CA and maintain it just for Cisco's MRA to work is ridiculous - as is Cisco's assumption that every customer must ...

So, assuming you're ONLY using the Expressways for MRA, you should be able to upload a cert to the C that does not have a Client EKU? You just upload the same cert (with only a server EKU) to both the client and server certificate areas on the EXP-C...

I'm trying to make sure I understand what actually changed in 15.5. Did breaking out the server and client certs separately just bypass the cert upload validity check on the EXP-E so that the EXP-E will accept a cert that has no Client EKU? If that...

I meant 15.4. It dropped as part of the "15SU4" UC drop of most things UC, but Expressway just sticks with its old naming convention. If Cisco is making a mistake in assuming that everyone has an internal CA. Many do not. My main issue is that ...
