Ghost Calls from Port Scanning

[Yealink Support]

Hi ctiefel,

You can try to add below syntaxs to your cfg template(M7 template) and auto-provisioning it.

1. You can try this syntax in CFG template.
---------------------------------------------------------------------------
#!version:1.0.0.1

#The x of the parameter "account.x.sip_trust_ctrl " ranges from 1 to max accounts. For example, x ranges from 1 to 6 of T28.

account.x.sip_trust_ctrl=1
------------------------------------------------------------------------------------------

When you want to enable this sip trust control for account 1, fill 1 to “account.1.sip_trust_ctrl”.
Then SIP messages from other servers will refuse by the phone.

2. If not, you can disable the “Allow IP Call” in webpage or auto-provisioning and try again.

-------------------------------------------------------------------------------------------------
#!version:1.0.0.1

#Enable or disable the phone to dial the IP address directly; 0-Disabled, 1-Enabled (default);
features.direct_ip_call_enable = 0

-------------------------------------------------------------------------------------------------

Please try again and feed back to me.
