We are running this in production with UCM 11.5, CCX 12.0, and Expressway X12.5.6 without any issues, CCM cores, or other problems.
If that core out bug is impacting in your version of the UCM then sure maybe avoid this, but at least per my own case we have not had any trouble with this path headers being enabled.

Clicking call control buttons in Finesse was successful in controlling the phone. So, while the documentation and field experiences maybe fuzzy, here's one empirical case of evidence that it does work on the latest versions. Frank, what did TAC respond to you with?

Finesse is using VPN, but the physical desk phone is not – it is connected via MRA. Standard inbound/outbound calling to the phone itself works flawlessly over MRA. What isn’t working are CCX calls to the agent phone; CCX uses CTI to control/monitor the desk phone. I did read the CCX/expressway design guide which generally states that CCX over MRA is supported, but features that rely on CTI-QBE are not. The documentation isn’t clear as to what CCX features rely on that. It does say CCX is supported however and in my mind the base feature required in order to say that “CCX is supported” would be routing calls to agents. I’ve asked TAC to confirm what CCX features/functions are available/supported and which are not? This is not critical as we do have the ability to use Jabber softphones via VPN, but we do wish to use 8800 series phones connected via MRA if possible. --- Frank Wakelin – Senior Network Analyst Information Technology | City of Richmond Office +16042764190 Mobile +17788394693 [email protected]<mailto:[email protected]> From: Aman Chugh <[email protected]<mailto:[email protected]>> Sent: March 17, 2020 7:45 PM To: Wakelin, Frank <[email protected]<mailto:[email protected]>> Cc: Erick Bergquist <[email protected]<mailto:[email protected]>>; Lelio Fulgenzi <[email protected]<mailto:[email protected]>>; voyp list, cisco-voip ([email protected]<mailto:[email protected]>) <[email protected]<mailto:[email protected]>> Subject: Re: [cisco-voip] CCX phone agent over MRA? It should work if CTI from Finesse is using VPN. Are you able to make inbound and outbound call to the MRA phone without Finesse. For the inbound call Cucm sends an invite over to Expressway C with which the mra phone is registered. I would pull CUCM and CTI trace for the inbound call.
