I have one sip account with 3 different phone numbers.
The phone number which gets called is transmitted in the to header.
So I was happy to find the parameter sip.disp_incall_to_info in the admin manual and imported it: sip.disp_incall_to_info = 1
The problem is that it doesn't work. The display of incoming calls didn't change and I still don't know which number got called.

Is this a known problem or does this option work for someone?

Please enable this parameter to display the callee on the screen.
phone_setting.called_party_info_display.enable = 1

Best Regards,
Simons
