If i understand you well...
You need to create 3 tables, if you want to create many-to-many relationships between owners and phones:
1) Supliers_phones
2) Customers_phones
3) Vendors_phone
Each of it should contain 2 Foreign Keys:
1) Suplier/Customer/Vendor FK
2) Phone FK
But...
I'd suggest to normalize data by creating 4 tables:
OwnerType (OTypeID INT IDENTITY(1,1), ODescription NVARCHAR(155))
Owners (OwnerID INT IDENTITY(1,1), OName NVARCHAR(155), OSurName NVARCHAR(155), ONickName NVARCHAR(155), OBirthDay DATETIME, OTypeID INT (FK - reference to OwnerType table))
Phones (PhoneID INT IDENTITY(1,1), PNumber (?), PCompany (?), PAreaCode(?))
Owners_Phone (OwnerID INT (FK - reference to Owners table), PhoneID INT (FK - reference to Phones table))
Note: it's only suggestion ;)
