Grandstream GXP 2140 and GXP2200-EXT

I am having an issue setting up a Grandstream GXP2140 with the GXP2200-EXT sidecar. I have the config set for both in Endpoint Manager and when I push the config, the BLF lines I had programmed are not there. If I do it from the web page of the phone, they show up just fine. I don’t know what information you need but the phone firmware is

The other thing that is happening is when I reboot the phone, it won’t register until I remove the sidecar and then reboot it, wait for it to come up, and then I can plug the sidecar and everything works fine. Just another weird oddity.

Sounds like the 2140 is certified, but not the 2200?

You might need to reach out to the vendor to resolve with Sangoma.
