Jabber Guest Domains

[Gordon Ross]

In the installation docs for Jabber Guest, it says:

"Make sure that the domain has an associated DNS record that resolves to the Cisco Expressway-E"

Is this just making sure that the VCS-E has an A record (e.g. that vcs-e.example.com resolves) or that example.com must resolve to something? If so, exactly what's required?

Hello Gordon!

Yes I agree, the documentation also seems to me as not ideal and completely self explaining as well as the service itself.

How I read it: if your jabber guest domain is jg.domain.com you have to point A records for that

domain to your -E.

Please remember that you also need a firewall doing some port mapping 443>9443,

see the "Ports and Protocol" information

Now its your turn to rate this message with the stars below and set the thread to answered if it is!

I kinda tried something like that (I actually just did a CNAME) but I then got certificate errors (JG domain name didn't match VCS certificate), so thought that was wrong. Or is the documentation lacking and I have to manually add my JG name as a SAN to the Expressway CSR?

Please remember that you also need a firewall doing some port mapping 443>9443

I don't have anything in front of my VCS-E, so I don't believe I need to do anything. Unless you're saying that VCS-E port 443 needs re-writting to JG port 9443...?

Thanks,

Yes, this is what I say!

see the "Ports and Protocol" information

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/Guest/10_5/icg/JABC_BK_JA306F08_00_jabber-guest-install-and-configure.html

so https://jg.domain.com:9443 should work as well

OMG - The docs really are unclear on this!

From home, I've just tried https://vcs-e.example.com:9443/call/123@example.com That just came back with a "Not found on this accelerator" message. I'm guessing my domains are all in a mess. I'll have to try and unpick this on Monday :-(

Anyone found correct understand of what Cisco meant:"

Make sure that the domain has an associated DNS record that resolves to the Cisco Expressway-E. The domain

information is propagated from the Cisco Expressway-C to the Cisco Expressway-E through the SSH tunnel

(port 2222). The information is used by the Cisco Expressway-E to validate incoming HTTP requests for the

Cisco Jabber Guest service"

I need to know exact DNS record this is referring to. 

Any clear and concise document on how to set this up.

The Jabber Guest Server needs an A Record on the Outside Public DNS.

Depending on the links you use for your Jabber Guest Server would define the A records that would need to be in place on the Public DNS.

So for example.

Jabber Guest Server is named jabber.example.com

Expressway-E is named express.example.com

Expressway-E has a public ip of 8.8.8.7

The Domain used for Links I configured on the Jabber Guest Server is express.example.com

When someone uses a call link it would be https://express.example.com/call/1234

You would want an A-Record for express.example.com to resolve to the IP address of the Expressway-E External IP Address

In this example it would be an A record for express.example.com resolving to 8.8.8.7

OK. so what if the JG server is in an internal domain eg internal.local but the public domain is example.com? Can I have the JG FQDN as JG.internal.com, the links domain as JG.example.com and have a public A record resolve to the public IP address of EXP-E?

Thanks
