Hello, the main-account number is *2890
but who can i recieve calls by direct number *2892

if i call the direct number *2892, all calls go to *2890

Regards

Did I understand correctly that 2890 is displayed in INVITE, and another number is displayed in TO: 2892

At the same time, it is necessary route to 2892 for an incoming call?

If so, see the instructions

Unfortunately, they are only in Russian, use a translator:
