Anonymous internal CLI

I will need to configure a freepbx so that when transferring calls to the internal ones, it doesen’t pass the CLI or the internal number but just anonymous?

Can you help me with this configuration?


Use the SetCallerID module and route the call through that.

Thanks Dave for your suggest.
The module works fine.
I have to use it for intercom calls and I used MISC APPLICATION by creating a service code “1201” with destination set caller id where I get anonymous calls inside 201.
When I transfer a call using the BLF key at 1201, extension 201 receives the anonymous call but does not turn on the BLF key light.
How do I see the status of code 1201?
