Hi guys,thanks for giving us

Hi guys,

thanks for giving us this opportunity to dig deeper into MRA feature! Here is my question: can you please elaborate or point to the right places where we can find more about three key capabilities that make MRA possible:

- XCP router for XMPP traffic

- HTTPS reverse proxy

- proxy SIP registrations

This info was part of the presentation I attended during Cisco Live event but never had a chance to hear anything more about "three key capabilities".

Thanks,

Tenaro

Hi Tenaro,   I would like to

Hi Tenaro,

   I would like to know what specific details you're looking for those features as there aren't any documents that dig deep into the specifics of these features. Here's the ciscolive presentation - http://www.cisco.com/web/HR/ciscoconnect/2014/pdfs/20140403_cisco_connect_see_expressway.pdf

Thanks for providing the

Thanks for providing the right link, I'm referring to the slide 13 in that presentation. Can you please explain what is XCP Router or what is the purpose of the "HTTPS Reverse proxy"? Are all "3 key capabilities" always necessary for MRA feature to work? What if we are using Jabber for Windows client in phone-only mode?

Can we compare yellow cylinder in that picture with the SSH tunnel that is mentioned in Expressway's GUI (under Status -> Unified Communications -> View ssh tunnel status)?

Is there are way to see separately status of every of these 3 key capabilities?

Thanks,

Hi Tenaro,    I'll try and

Hi Tenaro,

    I'll try and answer it to the best of my knowledge. There aren't any documents that provide details on the same.

 

XCP Router : This is required for XMPP routing of data to CUPS server. It routes XMPP data to the other active XCP services on Cisco Unified Presence.

 

HTTPS Reverse Proxy : This service helps communicating with CUCM & CUPS in the internal network and that is why a discovery of CUCM, CUPS is done on Exp-C. The internet communicates to Exp-E which is an element sitting in the DMZ, Exp-E has a secure traversal zone with Exp-C which has visibility of CUCM & CUPS internal servers. So it acts as a proxy for external Jabber clients. With that being said, the role of Reverse Proxy is limited to Collaboration Edge and is not a general purpose reverse proxy for other applications.

 

Proxy SIP Registrations : This is similar to HTTPS Reverse Proxy in the sense that this feature enables endpoints to register to CUCM.

 

All three are required for Collaboration Edge and there's no serviceability to disable either of the services.

For Jabber Phone-mode, I see no restriction on it not being supported with Collaboration Edge. For such a deployment, CUPS discovery won't be needed as Presence is not needed in Phone-mode.

Forgot to mention, the SSH

Forgot to mention, the SSH tunnel is nothing but connection to Exp-E, so yes the yellow cylinder in Slide # 13 is depicting that tunnel.

Re: Forgot to mention, the SSH

Hi,

 

just want to check, for expressway-e mra, support 3rd party reverse proxy deployment?

Hello Both,

Hello Both, Are we good to go with Jabber for guest to deploy for customers?.A separate server is required right?..Can you please provide specific design documents for Jabber guest..?

Great question,I was told it

Great question,

I was told it should be supported with X8.1.1 but now I'm not sure anymore. Is it out yet or it will be part of X8.2? When can we expect X8..2?

Guys,

   Jabber Guest will be available from x8.2 and I'm checking internally to get an ETA on FCS.

I have two more questions,

I have two more questions, both related to licensing:

1. Let's imagine customer has CUCM 10.x and don't know anything about Expressway product line, but is currently using 100 Jabber for Windows clients together with the VPN clients. Can customer download/install/license/configure Expressway Core plus Edge and start using same 100 Jabber clients (and no VPN clients anymore) without ANY new costs?

2. Status Overview page in Exp-E (attached) is making distinction between Unified CM calls and RMS calls. Can you please explain the purpose of RMS call type: as far as I understand Expressway devices are not capable to register endpoints (that's the main difference when compared with VCS product line), instead EXP-C/E combination is tunneling Jabber clients through the firewalls so it can stay registered with the CUCM. Can you please explain then why should we buy RMS licenses if we have same scenario as in first question?

Thanks for all previous answers!

Beginner

Hi Tenaro,   For query 1, I

Hi Tenaro,

   For query 1, I would appreciate if you could reach out to your Cisco Sales Representative and discuss the same.

 

For query 2, Rich Media Session (RMS) licenses is optional for Expressway and is used only for Jabber Guest or B2B Video. If your deployment is for VPN-less Jabber, this license is not required and infact doesn't even come with regular Expressway licenses. Only Unified CM Calls section is used, if you make a call and view the status page, RMS should show 0 and Unified CM should show 1. I would suggest having a look at the Cisco Live Expressway slide deck and refer to slides 21, 22, 25 and 26.

Does the Cisco Collaboration

Does the Cisco Collaboration Edge Architecture offer High Availability?  We would want this to be available in a DR scenario so users could still tunnel in if the primary data center is offline.  Our future goal is to have our Publishers in our main datacenter with subscribers at our DR site.  We would have PRI access at both sites.  Just trying to figure out how Cisco Collaboration Edge Architecture plays into our DR.  Thanks.

Hi Sriley,   Yes, Collab Edge

Hi Sriley,

   Yes, Collab Edge does offer high availability. The scenario is very much possible. Please have a look at the following guides to

Cisco Expressway Cluster Creation and Maintenance Deployment Guide, Release X8.1.1

Hi,I have a situation for MRA

Hi,

I have a situation for MRA, where internal and external domains are different,

eg  :

internal domain is example.net  ( resolvable from intranet)

external domian is example.com ( resolvable only from internet)

 

Can you advice if there any specific  steps to be followed,  Attached the jabber error report

 

Regards
