In this configuration there is only one telephone line available (e.g., +53043515094) in the server computer to receive incoming calls. The number of telephone lines directly affects the possibilities a client computer has to establish connection with the server computer in an environment where more than one client computer are struggling among themselves to establish a dial-up connection with the server computer. To prevent this issue from happening, it is innevitable for the server computer to provide more telephone lines for incoming calls (at least one for each user the server computer expect to receive incoming calls from). Sadly, that is not possible at present time.
