[cisco-voip] webkit fun!

[Lelio Fulgenzi]

Unfortunately, in order for us to deploy Jabber with MRA, we needed split view DNS and to get that, we needed to deploy a secondary set of delegated DNS servers configured with split view DNS, hence the servicedomain.acme.com.

We won’t be able to enable split view DNS on our primary DNS servers. Just not an option.

So, because of this and because of how these roomkits build their SIP URI, I have no choice but to use servicedomain.acme.com as the OTLD.

Well, I guess the two are not really connected, but in our case the O365 team gobbled up the acme.com SIP SRV records too, so that’s why we really need to use the servicedomain in the OTLD.


Still confused as to why it’s working for the SX20/TC but not the RoomKit/CE.

I have always set my OTLD to acme.com<http://acme.com> and my cluster FQDN to *.acme.com<http://acme.com>

Or if I'm using a subdomain for my CUCM I do an OTLD of acme.com<http://acme.com> then in cluster FQDN I put *.telecom.acme.com<http://telecom.acme.com> *acme.com<http://acme.com> (space seperated)

I could be doing this completely wrong but it's always worked in the environments I've set up.

Alright – fixed the enterprise parameter (although I really would like to know what else this affects), but I still can’t get inbound calls to work.

I have another device, and SX20, working with inbound extension only dialing, it used to have the SIP URI of DN at hostname.acme.com<mailto:DN at hostname.acme.com>, but it’s now DN at servicedomain.acme.com<mailto:DN at servicedomain.acme.com>. But inbound dialing still works.

The transform on the expressway C says, if someone calls DN at servicedomain.acme.com<mailto:DN at servicedomain.acme.com>, transform it to DN at acme.com<mailto:DN at acme.com> and send it to the neighbor zone.

The SX20 is running TC software vs CE software.

Organization Top Level Domain: servicedomain.acme.com<http://servicedomain.acme.com>
Cluster Fully Qualified Domain Name: acme.com<http://acme.com>

Does the CE software require the phone to only be addressed using the full SIP URI it know about? I can’t imagine such a limitation being imposed.

The C search results report Not Found. ☹

Ugh – enterprise parameter top level domain. Yuck.

I’m ok with that – the more I can do on CUCM the better in my opinion. But I’m not sure where to set the SIP URI for the device in CUCM.

Yea, it will overwrite it with the CUCM configuration.  You can try turning off provisioning and point it manually to CUCM.

Alright, got this webkit registered, both on-prem and through expressway. My testing while on expressway wasn't going so well, so I'm going to concentrate on on-prem first and certify all functions then move to expressway registration after that.

Biggest thing is that the SIP URI shows as DN at cucm-host.acme.com<mailto:DN at cucm-host.acme.com><mailto:DN at cucm-host.acme.com<mailto:DN at cucm-host.acme.com>> which is causing me nothing but grief. This SIP URI won't work because we need to use the service domain to get calls in but this is what shows during proximity. Yuck.

I've tried changing it but it still doesn't work and it changes with every reset/re-registration.

I've tried adding SIP URIs in the user setup and on the DN setup but to no avail. For some reason, I think this is even breaking just DN dialing, using DN at servicedomain.acme.com<mailto:DN at servicedomain.acme.com><mailto:DN at servicedomain.acme.com<mailto:DN at servicedomain.acme.com>> which was working to my SX20 without any SIP URI configuration, although the SX20 is using TC software, not CE.

I'm going to break out the admin and user guides, but thought I'd ask.

Also - what's the rule of thumb with setting things in CUCM Device Config Page vs Device GUI? It seems like I can change things on the device GUI, but if the setting exists in CUCM Device Config Page, that value overwrites on next reset.
