I have two companies (A and B) that uses the same UC520 router.
Company A uses 12345100 for their main line and B uses 12345200.
There is only one reception that answers for both companies. The receptionist has 12345255 as their number. When someone calls from outside to company A or B it gets forwarded to 12345300. However receptionist only sees the outside line and doesn’t know whether call is for company A or B.
Is it possible to set the router so that receptionist can see that a call forwarded to 12345255 is for 12345100 or 12345200?
Looking forward to pointers and directions.
