Communication apparatus for multi-session communications, control method therefor, and storage medium

A control method for a communication apparatus capable of conducting fax communications via an IP network using a plurality of sessions, the control method comprising:

• an acquisition step of acquiring a receive session count which indicates the number of sessions set to be used exclusively for fax reception when the plurality of sessions include any unoccupied session which is a session available for fax communications;
• and
• a transmission starting step of determining whether or not sessions corresponding in number to the receive session count acquired in said acquisition step are able to be secured as the receive sessions, and starting fax transmission using the unoccupied session if the sessions are able to be secured.

A computer-readable non-transitory storage medium containing a program for causing a computer to implement a control method for a communication apparatus capable of conducting fax communications via an IP network using a plurality of sessions, the control method comprising:

• an acquisition step of acquiring a receive session count which indicates the number of sessions set to be used exclusively for fax reception when the plurality of sessions include any unoccupied session which is a session available for fax communications;
• and
• a transmission starting step of determining whether or not sessions corresponding in number to the receive session count acquired in said acquisition step are able to be secured as the receive sessions, and starting fax transmission using the unoccupied session if the sessions are able to be secured.
