Image communication apparatus, server apparatus, and capability exchanging method

摘要

An Internet facsimile apparatus 11A as a sender makes inquiry about capability, which a destination Internet facsimile apparatus 11B possesses, to a local server 13A in a local network 10A. When the local server 13A has no capability information of the destination stored, the sender makes inquiry to a DNS server 16 higher than the local server 13A and obtains capability information of the destination from the DNS server 16. Then, the sender registers the obtained capability information of the destination to a memory, which the local server 13A or the sender has. This realizes that the sender can surely obtain capability information of the destination. Also, this makes it possible to automatically register capability information of the destination to the memory of the local server 13A or the sender.
