Oh yeah, I forgot to mention one thing. We were on CUCM 11.5(1)SU2 and it 
didn't need this setting on Expressway. We had to do an emergency upgrade to 
11.5(1)SU6 to stop CUCM bleeding out from too many Jabber clients, and this 
version did need the setting on Expressway. If this change was documented 
somewhere, I didn't know where. So that was great.

The symptom we were troubleshooting was that CUCM would try to ring the MRA 
phone, and Expressway would return 404 (on behalf of that phone). We toggled on 
the header option and reset the phone to fix it. Hope that level of detail 
helps someone.

Absolutely, here’s what Aman sent me:

Anther thing of note is use of SIP Path header on Expressway C. This may be

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

Um, so, outside of ccx, getting multiline 8800s working over MRA requires extra 
config?

Can you share any tech notes ?

Yeah, once again as it turns out it was the Cisco TAC engineer not really

also never escalated the call to someone who does when the question was over

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

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.

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?
