[cisco-voip] TP Room Endpoints - Name and Number on TV Display

[Ryan Ratliff (rratliff)]

I’d recommend setting the System Name on the Device page for the C20.  That will sync up with the endpoint’s local setting and avoid any interop issues with the Line value.

Hi All,

I am wondering if anyone has solved a certain problem for endpoints which are registered to CUCM.  You know how the system will show a name for the device at the top left of the TV screen?  I'm not talking touch 8 or touch 10 here, but the actual TV or monitor display.

I would like to show a combination of the name of the room and the phone number as well, but I'm not finding a very good solution to do this.

I did notice that what shows up by default is from CUCM DN Display field, so I edited it.

Instead of just this:

I used this:

And that works, but then I face two challenges:

1) Internal Caller ID is really long and redundant, containing the DN in itself

Plus, the documentation says you shouldn't put a number in here, probably for the same reason I'm saying (not good practice):

2) Or the whole thing is just too long and over the character limit, like this (note I cannot fit the rest of the number):

So, that's less than ideal, but atleast it's persistent through reboots of the codec.

A non-persistent approach I did try, is changing the Codec's SIP DisplayName, which by default is populated with what's in CUCM's DN Display field:

From the default:

To this:

And that works too, but then it's volatile and I have to keep changing them back all the time, and checking up on them, bleh.  No thanks.

I did look into the start up script option on a TC7.3 C20 codec, so the system can reconfigure its own DisplayName when booting, but that didn't work with the below simple script, despite working when manually clicking Run. I think it didn't work because of the order of operations: 1) boot codec, 2) run script and update display name, 3) register with CUCM, 4) re-update display name from CUCM

So anyway, I've done some searching, but not really knowing these systems too well or the terminology, I'm kind of stuck.  I suppose I could write a script in Python and have it check the config and update, and set that to run every 10 minutes or whatever, but I don't know.  Maybe.

I'll leave it there and see what you all have seen or done.  Thanks much.
