I am getting unsolicited IP calls. Is there a way to block IP calls while still being able to receive calls from my SIP provider?

Thanks

Hi，
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

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


You can refer to below Auto Provisioning guide to get more information:
