Hello,

I am getting ghost calls on a SIP-T38G and was not able to find a firmware version with SIP Trust Control.
Also I was not able to modify the existing config to add Sip Trust.

Thanks,
NDurain
Hi Ndurain,

You need to enable the fucntion through autoprovision in T38G. It can't be configured in web UI.
Please check this FAQ, check the second method(autoprovision)
