[cisco-voip] access to service subscription when publisher down...

[Ryan Ratliff (rratliff)]

What is the value of your Enterprise Service?

The default services that start with “Application:Cisco” are the ones that the phone interprets and will always be an https connection to the server the phone is registered to.

The 7940/60 phones don’t support the Device->Device Settings->Phone Service configuration (called Internal Service Provisioning) so always use Enterprise Parameters.  The newer phones do support them and if internal services show up in the config file they will always be preferred over the Enterprise Parameters.

Thanks Brian. Right now, it's set to "both".

The 7942/62 have the same Services URL programmed on the phone config page as the 7940/60, but this is overridden by the enterprise service url subscription. I know/assume this is the case, because when I go to the phones web server to look things up (or on the phone itself) the service URL is not what I have entered on the phone config page.

Lelio,

It depends on what you have selected for Services Provisioning.  If you have it selected to Internal under Enterprise Parameters, it communicates with the registered subscriber for things like Directories and such.  If you set it to External Services Provisioning, it uses the Services URL.

For services not built-in, it gets them via the config files via TFTP.

For the 7940/60 phones, I was able to point to a particular server for a service list in the event the publisher is down so they can still use this one service. In the XML file, I then pointed back to the publisher for the list of subscribed services.

The 7942/62s don't work this way, since the service URL is overwritten by the enterprise wide service url subscription that we enabled when we upgraded to v7.

The question is, does the 7942/62 have it's list of services at boot up or does it still communicate with the publisher to get it's list of services? Or does it request it from the subscriber it's connected to? Our lab only has one node (pub) so I can't test this.

Thanks!

Lelio
