Hi,

Please change these two settings by auto provision :
Set two parameters via auto provision. The auto provision sentences are as follow:
#!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 2 of T20.
##When you want to enable this sip trust control for account 1, fill 1 to “account.1.sip_trust_ctrl”.
account.X.sip_trust_ctrl=1
##Enable or disable the phone to dial the IP address directly; 0-Disabled, 1-Enabled (default);
features.direct_ip_call_enable = 0
