Calls ghosts T21
Hello I have a T21 with firmware 34.72.193.20 and receive calls 24x7 ghosts, I contacted my dealer and I sent a guide for auto-provisioning to change parameters that do not appear in the web interface of the phone.

I do not really understand the English and do not understand what I have to do, in the web of phone I have Allow Ip Call = disable, have to make changes more? or there is a new firmware to solve this error?

A greeting.

RE: Calls ghosts T21
Hello,

In T21, you need to enable sip trust control option through autoprovision to block ghost call:

account.1.sip_trust_ctrl = 1

Regards,

Hi, thanks for the reply, as this task is done ?, I saw the pdf on auto-provisioning but do not understand.
I could outline the steps?
A greeting.
