You definitely do not want _cisco-uds and _cuplogin on the outside from my understanding.  http://www.cisco.com/c/en/us/support/docs/unified-communications/expressway-series/117811-configure-vcs-00.html#anc10

Just collab-edge on the outside, plus any b2b/federation records you need.

I’m trying to deploy Expressway MRA and B2B.

We currently have an external DNS domain and a different internal domain.

For our internal domain which I’ll call andy.local we have the following SRV records setup.
_cisco-uds._tcp.andy.local 8443 10 10 sub1.andy.local
_cisco-uds._tcp.andy.local 8443 10 10 sub2.andy.local
_cuplogin._tcp.andy.local 8443 10 10 cups1.andy.local

For our External domain which I’ll call andy.com<http://andy.com>
_h323cs._tcp.andy.com<http://tcp.andy.com> 1720 10 10 videoconf.andy.com<http://videoconf.andy.com>
_h323ls._udp.andy.com<http://udp.andy.com> 1719 10 10 videoconf.andy.com<http://videoconf.andy.com>
_sip._tcp.andy.com<http://tcp.andy.com> 5060 10 10 videoconf.andy.com<http://videoconf.andy.com>
_sip._udp.andy.com<http://udp.andy.com> 5060 10 10 videoconf.andy.com<http://videoconf.andy.com>
_sips._tcp.andy.com<http://tcp.andy.com> 5061 10 10 videoconf.andy.com<http://videoconf.andy.com>
_turn._udp.andy.com<http://udp.andy.com> 3478 10 10 videoconf.andy.com<http://videoconf.andy.com>
_collab-edge.tls.andy.com<http://collab-edge.tls.andy.com> 8443 10 10 videoconf.andy.com<http://videoconf.andy.com>

We have an A Record for videoconf.andy.com<http://videoconf.andy.com> which points to our public address.

As it doesn’t work I raised a TAC case and the engineer changed my errors in the config, but also says I need to add _cisco-uds._tcp and _cuplogin._tcp for our external domain.
now I’m really confused as I thought that Jabber uses the DNS records to determine which side of the firewall it was by the dns records it receives when you boot the app.
Also videoconf.andy.com<http://videoconf.andy.com> needs to be changed to match the FQDN of the VCSe or Expressway Edge server.

We are running CUCM 9.1.2 with a single expressway-c and expressway-e running x8.5

TIA
