This is a new one for me. Do you have any idea what is requesting the extension be deleted?

The extension isn’t being deleted. The registered contact to the AOR is being deleted. This is classic NAT/networking issues.

It happens as a result of the device itself requesting the registration to be removed.

I’d suggest providing a SIP trace (pjsip set logger on) to show the actual traffic going on. As well - what is the device that is registering to this extension?

Hello,

There is the result of : pjsip set logger on

The device is a grandstream gxp2170

That’s a single successful result for qualifying. It doesn’t show the REGISTERs - which will likely show the Grandstream asking for the registration to be removed.
