Abstract
A facsimile apparatus includes a determination unit configured to determine whether a transmission destination is a gateway that uses a protocol for performing fax communication in real time on the IP network, and a control unit configured to perform control, if the determination unit determines that the transmission destination is a gateway apparatus, to transmit a packet of a smaller size and add a smaller number of redundant packets compared to when the transmission destination is not a gateway apparatus.
Claims21
An IP facsimile apparatus comprising:
- an interface configured to connect to an IP network;
- one or more processors;
- and
- a memory storing instructions that, when executed by the one or more processors, cause the IP facsimile apparatus to perform operations comprising:
- performing an IP facsimile communication by transmitting a packet via the interface;
- determining whether the IP facsimile communication is to be performed via a T.38 gateway apparatus or the IP facsimile communication is to be performed not via the T.38 gateway apparatus, wherein the T.38 gateway apparatus converts a packet of T.38 protocol to a G3 FAX signal;
- in a case where it is determined that the IP facsimile communication is to be performed via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet which is to be transmitted via the interface, to be a size which is able to be received by the T.38 gateway apparatus, and
- in a case where it is determined that the IP facsimile communication is to be performed not via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet which is to be transmitted via the interface, to be a size greater than the size which is able to be received by the T.38 gateway apparatus.

A method for an IP facsimile apparatus, the method comprising:
- performing an IP facsimile communication by transmitting a packet via an interface configured to connect to an IP network;
- determining whether the IP facsimile communication is to be performed via a T.38 gateway apparatus or the IP facsimile communication is to be performed not via the T.38 gateway apparatus, wherein the T.38 gateway apparatus converts a packet of T.38 protocol to a G3 FAX signal;
- in a case where it is determined that the IP facsimile communication is to be performed via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet, which is to be transmitted via the interface, to be a size which is able to be received by the T.38 gateway apparatus, and
- in a case where it is determined that the IP facsimile communication is to be performed not via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet, which is to be transmitted via the interface, to be a size greater than the size which is able to be received by the T.38 gateway apparatus.

A non-transitory computer readable storage medium storing instructions that, when executed, cause a computer to perform a process, the process comprising:
- performing an IP facsimile communication by transmitting a packet via an interface configured to connect to an IP network;
- determining whether the IP facsimile communication is to be performed via a T.38 gateway apparatus or the IP facsimile communication is to be performed not via the T.38 gateway apparatus, wherein the T.38 gateway apparatus converts a packet of T.38 protocol to a G3 FAX signal;
- in a case where it is determined that the IP facsimile communication is to be performed via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet, which is to be transmitted via the interface, to be a size which is able to be received by the T.38 gateway apparatus, and
- in a case where it is determined that the IP facsimile communication is to be performed not via the T.38 gateway apparatus, setting a number of redundant packets for error recovery included in the packet to be transmitted via the interface such that a size of the packet, which is to be transmitted via the interface, to be a size greater than the size which is able to be received by the T.38 gateway apparatus.
