Don't expose the UCM to the public internet ? ... View more

You can enable accounting or similar but it has a CPU impact . RADIUS is one option as it cannot send CDR to the UCM, but in a later version only CMR. There is a call establishment rate type SNMP OID , but it’s not specific to which peer if you have many. That’s as far as I’ve gone with it, the ISR G2 is far more sensitive to this sort of thing and will tank the CPU than Id thought ... View more

I would also like to know , as the disconnect supervision is not great on these and it has a delay after the circuit is closed. ... View more

When you remove and re add a device by MAC , RIS status is shown in the CCMAdmin page. So, rejected (device type, security, etc) is shown. That’s based on the MAC previously as seen not necessarily as it is for the present configuration, as you’ve seen by waiting for a registration attempt ... View more

You need to provide more information about what you expect to happen, and what is happening.   "It boots up" doesn't explain anything, the phone is supposed to boot up after being reset to default. ... View more

James, We order the CP-8832-POE for this which is a grey rectangular brick that plugs into the Ethernet, and has a USB-C jack. It comes with a USB-C cable to connect to the phone. I worry that the brick will get lost when moving the phone around and have ordered a spare but it is what it is. >From my internal documentation: The Cisco 8832 can be powered from PoE, which is the recommended model to minimize daisy chains, and the number of cables. Order part CP-8832-POE= (stocked) for the PoE / USB-C power adapter, with USB-C cable. Part CP-8832-PWR= only provides power for use with Wi-Fi connectivity (not used, not stocked). Part CP-8832-ETH= (not stocked) allows for Ethernet with external AC power. I remember taking a minute to try and figure out what these do. As far as European power, it's possible that the wall part that comes with the ETH and PWR models (or the worldwide, the data sheet makes some comment about this) is a switching supply that takes the clip on pins to work with whatever locale the power is ordered in. The ATAs I believe are like this. The data sheet says "compatible with 802.3af and 802.3at" which is not really a good way to describe the device. I have a couple powered by the POE brick now, it reads as a Class 3 budgeting for 13.9W with CDP. Power detail shows it's drawn 9.0 peak and 7.0 idle but I don't know how much they've been used or at what volume level. I think you'd do just fine with the -POE part. Adam ... View more

It says something about pick one of the options when you order the non spare part. If you pick that part on CCW it asks you to configure it with a power source. The spare doesn’t come with any power adapter like you note, and the unit has only USB-C so we are back to boxes and bricks to power these, even with PoE. That’s for sure unexpected if you don’t read closely. ... View more

Unless you’ve made a change restricting presentation somewhere along the way , I would start by debugging my way in from the service provider at the router towards the UCM to see what’s actually sent , how , and where it falls off. ... View more

I believe the module SN and load info are visible on the phones internal page if it is connected to the device, and absent if only provisioned - aside from logging on the phone . I can check that later. You can visually observe this or automate it by polling XML data from the phone perhaps. ... View more

We typically use something analog from a vendor that manufactures devices for outdoor or other environments such as Gaitronics, Ramtel, Allentel, Talk-a-phone, or Ramtech or something. Not specifically in a freezer but outdoors in winter and such.    Most electronics don’t seem to be rated below 32F even though they may “work” , due to probably some sort of testing and rating requirement.    Getting into PoE heaters and things just seems to be pointless - save for “monitoring” though many of the analog phones have some ability to dial in and test if they are designed for call-out primarily.  ...

To do this internally, you would want to have your generic css_office, and create css_help_desk with a ! translation that modifies the calling party number, with its search as css_office or whatever . Implication of that depends on how that impacts CDRs if needed (I don’t know) or how your dial plan and CSSes are setup for line/device ... View more
