Trying to stay awake, with 100db purring going on.

@smartfiber it is all about matching impedance or other expected audio parameters.

Part of your issue is that you are using the VDD port.
That is not an audio output port, it is a 3.3V DC output.

And you are plugging it in to an output from your amp.

@goodtm said in Changing extension mapping in Endpoint Manager Asterisk:

@JaredBusch Is it necessary to specify the [endpoint] command? It works for me even without specifying this command [endpoint]. For example, sip notify reboot-yealink 4287 or sip notify restart-yealink 4287 (depending on what I specified in the configuration file)

You are using sip not pjsip. The commands are different.

That said, the chan_sip driver is dead, and has been for years now. You need to switch to using the chan_pjsip driver.

Your problem is a lack of understanding how EPM works.

When you use the update device button, a SIP NOTIFY message is sent to the extension.

Obviously, if you delete a mapping for Extension 123, but do not reset the phone itself, the phone will continue to be provisioned as extension 123.

When you reuse the MAC address for extension 124, which is not currently registered, there is no endpoint to send the SIP NOTIFY to.

Basically, EPM is using this asterisk command (assuming you have a Yealink phone) to tell extension 124 to check its config. But since 124 is not yet registered, nothing answers the message.

pjsip send notify reboot-yealink endpoint 124

There are various contexts for different manufacturers

You can manually tell extension 123 to check it's config (which will make the device check, and pull the new config file with extension 124.

You can see it not work since I have no 124 on this PBX.

But for an extension that exists...

You can see the notify message in sngrep

Are you sure it allows .Net 4.0 or higher?

SQL Server is SQL Server. Nothing has really changed with it in years other than the ability to now install it on Linux.

The noise cancellation works really good. I don't know about factory floor good, but real good.

Do you find the (roughly) 500' range to be accurate? I only need 100' but with a few walls in between.

Walls hit Bluetooth pretty hard.

The model I linked is DECT.

Yes. I get 200' + from my office walking up or down the sidewalk.

What mobile site layout issues? I have no issues with the site on mobile.

It takes six months or so just for the US to produce the necessary paperwork to file!

fucking US immigration process is a dumpster fire.

@Fredtx If you are going to do VPN, then do hub and spoke for sure. Mesh of multiple locations like you have is simply asking for crypto to hit all the things.

I mean your risk is already high by using insecure LAN methods, but yeah, why multiply it?

macOS Server discontinued after years on life support

Apple is finally killing off the venerable macOS Server, directing users still clinging to Profile Manager toward Mobile Device Management solutions.

The move is arguably long overdue. Much of what made macOS Server a server was deprecated in 2018 as the company announced plans to stop the likes of DHCP and DNS in its product and directed users to handy open-source alternatives.

Umm what? Apple bought them last year.

Yes, and shut them down today. They were still operating like a separate company, though. But now they are gone.

Meh, don't care about a company staying separate year+ after acquisition. The product still exists though. Or was that cancelled as well?

Learning about provisioning Yealink phones

#1 thing to know, keep the cfg files to only things you are changing from default.

A few tips:

1. Using %NULL% in a value makes it "default"
2. Using %EMPTY% makes it an empty string
3. Learn about, and make use of, the y000000000000.boot file
