That's correct, there's no requirement between Unity Connection 8.0 and 8.5 to apply a new license file. Cisco's Upgrade guide confirms it here, you'll see the Note section reads: Note      Upgrading from Connection 8.0 to 8.5 does not require a new license file. ... View more

Assuming that within Enterprise Parameters you're specifying the URLs by IP address rather than hostname, you might be coming up against problems with the Trust Verification Service, an (awkward) addition since version 8 of CUCM. If your phones aren't picking up a valid ITL file, you can see that Host Not Found message. We've had the same issue, and had to manually delete the ITL file on each phone to get it to regenerate it as Cisco TAC couldn't provide any alternative. Hopefully this isn't what you're facing, but on an affected phone, press Settings, then 4, 5, 2, and then * * # to unlock the phone, and select Erase. If it fixes it, then get ready to have that combination of numbers stuck in your head as it is in mine! ... View more

As Ethan says, the registry key is required before CUPC 8.5 will work with WebEx, but you may also want to check that you're not losing any functionality within Meeting Center when starting WebEx meetings this way. There is a bug which Cisco is aware of that may mean you don't get access to video within Meeting Center, and you may find that audio participants are not announced even if that is your default WebEx site setting. ...

These instructions apply to Unity Connection, but I imagine there are similarly placed options under Unity. You may have to do a little more searching if you don't see the exact options I mention here. In the menu under 'Telephony Integrations' look under 'Phone System'. You may see a message that says "One or more port groups need to be reset". If you see that message, go to 'Port Groups' again under 'Telephony Integrations'. Look under the 'Needs Reset' column. For any port group that says 'Yes' under this column, click on the port group and then click the 'Reset' button. Regardless of whether or not this was needing done, you will maybe need to go back to 'Phone System', click on the name of your phone system, and then click the 'Run' button against 'Synchronize All MWIs on This Phone System'. This may fix your issue as it will go through all users making sure that the MWI status is correct. You can optionally just do this for one user by going into that user's settings, going to 'Message Waiting Indicators' and choosing 'Reset All', but you probably want to make sure this is fixed for all users rather than just those that have reported the issue. ...

This is, I think, due to the restrictions with integrating MP with WebEx. You can't have more than one WebEx account with the same email address, so any admin accounts on WebEx have to be distinctive or they'll be overwritten when the user with that username/email address logs in to use WebEx as a user. ...

I think it took around a week when we did it, but once that contact is made from your new WebEx account manager, responses are quicker. ... View more

Cisco needs to get a lot better at making both their customers and their TAC support personnel aware about their own products. We went through a similar long drawn out process trying to find out why this doesn't work, only to find out a lot later on that Type 2 WebEx doesn't work with CUPC 8 for any type of meeting, scheduled or unscheduled, despite being Cisco's recommended solution for all new customers. It may come in future versions of CUPC 8, but it certainly isn't available at the moment. ... View more
