T19P ghost call

[secureip]

Hi, I have 5 T19P phone with Firmware version 31.72.0.76.

I receive about 10 ghost call each hours. They are not loggued into the pbx. I also desactivated the Allow IP Call. I see many option like Acception SIP trust only server but I don't have it in my phone. Help !!!

First, do I have the latest firmware version?
Second, What I need to do?

Thx

Hi

To the ghost call, please add the two parameter through autoprovision to block it.

account.X.sip_trust_ctrl=1(replace the X with your account digit)

features.direct_ip_call_enable = 0

There is a FAQ describing this issue.

To T19, there is no a web option and you will need to do it through provision.please refer to the auto provisioning guide,
