Ghost Calls from Port Scanning

[Wilson_Yealink]

Hi elementpbx/jtcary,

Please enable the sip trust control, this is important step to solve ghost call issue. You can enable the sip trust control firstly, if the issue can't be solved, then disable the IP call feature.
You can try this syntax in CFG template.

Code:

#!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 5 of W52P.
​#You need to confirm which line you used.
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.

We have released the V73 betas version, please upgrade your firmware version to it then check the issue whether still exist after above step.
