1. A communication system comprises:
a first communication device configured to connect to a local area network (LAN); and a second communication device configured to connect to the LAN, wherein the first communication device comprises
a first processor, anda first memory storing computer-readable instructions, the instructions, when executed by the first processor, perform processes comprising:
a first communicating operation communicating from inside the LAN with a conference server via a proxy server to establish a session for a remote conference between the first communication device and the conference server using a first proxy setting, the conference server being provided outside the LAN, the proxy server being provided inside the LAN, the first proxy setting being stored in a storage device of the first communication device and being a setting to communicate via a specific proxy server;a first determining operation determining whether the session has been established using the first proxy setting by the first communicating operation;a second determining operation determining, in response to the determination by the first determining operation that the session has not been established, whether LAN information identifying the LAN is included in history information stored in the storage device, the history information being information in which device information identifying another communication device with which a remote conference was held and a specific LAN information identifying a specific LAN to which the other communication device is connected are associated with each other;a first transmitting operation transmitting, in response to the determination by the second determining operation that the LAN information identifying the LAN is included in the history information, setting request data to the second communication device identified by device information associated with the LAN information in the history information, the setting request data being data to request a second proxy setting and being data that includes at least first device information identifying the first communication device, the second proxy setting being a setting to communicate with the conference server from inside the LAN via the proxy server; anda second communication operation communicating, in response to receiving of the second proxy setting from the second communication device, with the conference server to establish a session with the conference server using the received second proxy setting, and wherein the second communication device comprises
a second processor, anda second memory storing computer-readable instructions, the instructions, when executed by the second processor, perform processes comprising:
a third determining operation determining, in response to receiving of the setting request data from the first communication device, whether to transmit the second proxy setting stored in a storage device of the second communication device to the first communication device, based on the first device information included in the setting request data; anda second transmitting operation transmitting, in response to the determination by the third determining operation that the second proxy setting is to be transmitted to the other communication device, the second proxy setting to the first communication device. |
