XMPP Federation via VCS-E

[nchandran]

Hi all,

I am trying to get xmpp federation going with a partner organization and I am stuck with the public DNS records that the documentation states, in particular for Group Chat. According to the documentation (http://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/vcs/config_guide/X8-5/XMPP-Federation-with-Cisco-VCS-and-IM-and-Presence-Service.pdf )- pg 15 . It mentions that an _xmpp-server SRv record needs to be created for the chat node alias pointing it to the VCS-E. My question is can this be a CNAME instead i.e :  primary-conf-server.domain     CNAME       vcse.domain

Or does it need to be an SRV record I.e two SRv records pointing to my VCS-E .

Setup:

VCS-E / C -8.5

CUCM 9.1.2

CUC9.1

CIMP&P-9.1

Any help is appreciated!

Cheers

Navin

Hi Navin,

If we're extending our persistent nodes out to the Internet, then we'll also need an xmpp-server SRV pointing to the VCS-E. See example below.

> _xmpp-server._tcp.acmecorp.com

Non-authoritative answer:

_xmpp-server._tcp.acmecorp.com   SRV service location:

          priority       = 0

          weight         = 0

          port           = 5269

          svr hostname   = devexpe01.acmecorp.com

> _xmpp-server._tcp.devpchatnode01.acmecorp.com

Non-authoritative answer:

_xmpp-server._tcp.devpchatnode01.acmecorp.com    SRV service location:

          priority       = 0

          weight         = 0

          port           = 5269

          svr hostname   = devexpe01.acmecorp.com

> set q=a

> devexpe01.acmecorp.com

Non-authoritative answer:

Name:    devexpe01.acmecorp.com

Address:  12.13.14.15

Also, we'll need to make sure that we've added the chat node alias to the subject alternative name on the certificate we're using on the VCS-E.

Hope this helps -
