Blocking Robocalls outside of Google Voice

I use and OBI 203 with GV as the service provider

I have been receiving lots of robocalls but they are not coming in via GV, instead they are coming in directly through the OBI.  I don't know much about how OBI works, but the robocalls seem like they are through an OBI to OBI route.

I would like to set up my OBI account to block all calls that do not come via GV, is there a way to do that?

Not sure how this helps if OP only has a GV (XMPP) configuration?
If the OP thinks they are not coming in as GV calls they can only be Obitalk or SIP.  Obitalk ones are too easy to trace back and how many robocallers know about Obitalk? So if he has no SIP providers configured it is much more likely that they are direct SIP to his OBi202.


Check the OBi call history to see where these calls are arriving.
To access Call History:
Log directly into the OBi using the local interface.
Key the IP address of the OBi into a Web Browser and hit Enter
The UserID and default Password are both "admin".
Click Status on the left column then click Call History.

Scanner calls are SIP routed to your Public IP Address and the port numbers of the OBi trunk definitions. Block these calls by using OBi Expert to make the following change on all your defined trunks. GV is currently XMPP and won't accept these calls, but GV will probably be converted to SIP in the near future.
