Solved Extensions are calling themselves for no apparent reason

Hello, I am using 3cx v18, but I have an issue. Extensions are calling themselves for no apparent reason. For example, extension 111 is calling 111. Why is this happening?

Hello there,

Are you using IP phones and if yes, which is the brand and model and provisioning method?

Thanks reply me,

Yes i use IP phone.

Phone model : GXP1625
part number : 9620008022A

Provisioning: manual

Manual provisioning is not something we support in addition to the fact that the specific phones are 3rd party supported as per our guide here. It is highly recommended to use fully supported IP phones provisioned with a router phone or 3CX SBC, or the 3CX clients (Webclient, Desktop app, PWA, 3CX mobile apps).

There are too many phones, so I should find another way, thank you

The problem you describe is a known issue which happens on old Grandstream GXP firmware.

Upgrade the firmware to the latest and it should go away.
