Image forming apparatus capable of controlling file transmission, control method therefor, and storage medium

A control method for an image forming apparatus, comprising:

• establishing a communication with an external apparatus using a call control protocol and first destination information of the external apparatus;
• obtaining, during the established communication with the external apparatus, second destination information of the external apparatus from the external apparatus, the second destination information being different from the first destination information;
• and
• displaying an operation key which enables data transmission to the obtained second destination information of the external apparatus without manual input of the second destination information by a user.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for an image forming apparatus, the control method comprising:

• establishing a communication with an external apparatus using a call control protocol and first destination information of the external apparatus;
• obtaining, during the established communication with the external apparatus, second destination information of the external apparatus from the external apparatus, the second destination information being different from the first destination information;
• and
• displaying an operation key which enables data transmission to the obtained second destination information of the external apparatus without manual input of the second destination information by a user.

A communication apparatus comprising:

• a storage device;
• and
• a processor configured to execute computer executable instructions recorded on the storage device, the computer executable instructions including instructions, that when executed by the processor, cause the communication apparatus to:
• transmit a connection request to an external apparatus using a call control protocol and first destination information of the external apparatus;
• receive, from the external apparatus, a response to the connection request;
• establish a communication with the external apparatus according to reception of the response;
• obtain during the established communication second destination information of the external apparatus included in the response from the external apparatus, the second destination information being different from the first destination information;
• and
• display an operation key which enables data transmission to the obtained second destination information without manual input of the second destination information by a user.
