摘要:
A system includes a switch responsive to a control module. The control module that determines whether an incoming telephone call from a telephone number to a telephone line is a facsimile call or a voice call and whether facsimile calls are authorized to be routed to the telephone line. When the incoming telephone call is a voice call, the control module instructs a switch to route the incoming telephone call to the telephone line. When the incoming telephone call is a voice call, the control module instructs the switch to route the incoming telephone call to the telephone line when facsimile calls are authorized, and to deny routing the incoming telephone call to the telephone line when facsimile calls are not authorized.

摘要:
A presence of a facsimile transmission tone generated by a calling party within a call is sensed for within a public telephone network before the call has been routed to a called party. If the facsimile transmission tone is present in the call, the telephone network denies completion of the call to the telephone line of the called party. If the call is absent the facsimile transmission tone, a telephone network switch is instructed to complete the call to the telephone line of the called party.
摘要:
Whether a facsimile transmission tone is within a call is detected before routing the call from a switch of a telephone network to a first telephone line. When the facsimile transmission tone is detected, whether an incoming facsimile transmission transmitted by the call is permitted to be routed to the first telephone line is determined based at least partially on restriction information. Routing of the call from the switch to the first telephone line is denied when the incoming facsimile transmission is not permitted to be routed to the first telephone line.
