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.

It should affect all clients which are registered over MRA with multiple lines.

If you can do a tcpdump between expressway and call manager you will see a 404 and it would verify that. We didn’t see it on Jabber because we just hadn’t tried it - only needed multiple lines on hard phones.

Or you can just change the setting on expressway, reregister Jabber, and hope for the best. Depends on what kind of lifestyle you subscribe to, I suppose.

I was under the impression from our discussion below that this only affects the 8800?

But it affects Jabber too?

Absolutely, here’s what Aman sent me:

Anther thing of note is use of SIP Path header on Expressway C. This may be needed to turned on if you multiple lines on 88xx phone. I have seen an issue when were we not able to ring second line on the phone when this was turned off on Expressway C.

You will need that turned up on Expressway C under unified communication - configuration.

I ran into this in testing in my environment few days back.

There are certain version requirements to have this turned on with CUCM.  Page 33

Yeah, once again as it turns out it was the Cisco TAC engineer not really knowing the product they are apparently supporting – which is fine, but they also never escalated the call to someone who does when the question was over their head either. – heavy sigh –

As it turns out we generally configure all of our agents contact centre lines as their second line.  After my post Aman reached out to me with a note about the use of the SIP Path header on Expressway C as this is needed to support multiple lines on 88xx phone. The lack of multiline support was what was killing the call to the agent extension (on the second line of the phone) when it was presented by CCX.  I had a chance to enable the SIP path header today and successfully tested CCX.

So thanks all for your assistance and more so your insistence that this is supported/working in your environments.  Thanks Aman for the mention of the SIP path header!

Yep, remote control via SIP from CUCM.

I just tried this again but on a CUCM 11.5, UCCX 12.0 and Expressway X12.5.5.

I pulled the traces off of two phones: one on-prem, one MRA, and the messages were the same.

This was Finesse telling the phone (Agent ext 2000) to answer a call, and thus CUCM using out of dialog REFER containing remote call control commands to answer the call.

I could be confused but I don’t think the phones talk CTI or CTI-QBE, they just talk SIP/SCCP.  UCCX talks CTI to CUCM’s CTI manager which then tells the phone to do something.  I know CTI isn’t supported over MRA, but that is for deskphone control from Jabber, not the jabber softclient.

I have people using CCE via thin client talking to a MRA registered jabber.  Now that I think of it, they said you can’t use Jabber for mobile because as an agent device, but I would think that is some other limitation.

I’m not really sure – I have my doubts as well.  They sited the lack of CTI-QBE support as to why the CCX servers could not use CTI to control the phones connected over MRA.  The more folks that tell me they had it working with CCX, the more I think they just latched on to the phrase in the feature configuration guide and went with that.  It certainly wouldn’t be the first time TAC has given me a pat answer and been unwilling to escalate/troubleshoot with me. ☹

Just curious as to what makes it unsupported with 11.5 or what is added in 12 which makes it supported.

Does SIP phone doing MRA require support for certain sip headers which are only supported with CSR 12 or later.

I did have it working with CUCM 10.5 , UCCE 11.6 and Expressway 8.11.2

No, I wouldn't think it has anything to do with finesse.  Again the user had direct access to Finesse, no VPN or Internet exposure, just simply the user was on the network with the PC while the phone was on a public internet circuit.  I'd guess it has worked in previous versions, as it's been in the UCCX SRND for a while now, but perhaps there's some issues with it.  I just wanted to add a story of success to this otherwise long thread of failures.

For whatever it's worth, I just upgraded a customer from CSR 11 to CSR 12.5 (including UCCX), and testing of an Agent phone registered over MRA with the Finesse client directly accessing Finesse server worked.  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?

Thanks for the reply.    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.

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.

I use Jabber as a softphone on the laptop the call is presented no problem.  Any ideas?

Has anyone done a Agent with a hard phone over MRA (8865)?   Finding
the documents don't really come out and say if it is supported or not.
See the notes about expressway versions and that is about it.

How about extension mobility login on MRA hard phone for agent use?

Jabber for Mac and Jabber for Windows cannot provide deskphone control over MRA, because the Expressway pair does not traverse the CTI-QBE protocol. However, if these Jabber applications, or other CTI applications, can connect to Unified CM CTIManager (directly or through the VPN) they can provide deskphone control of MRA-connected clients.
