Calling methods and devices

A server associated with a telephone, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• establish a data channel with a terminal for assisting a call, when the telephone is conducting the call with the terminal through a voice channel;
• and
• exchange interaction information with the terminal through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the telephone in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the terminal includes:
• transmitting first interaction information to the terminal through the data channel;
• when the first interaction information includes a service-information page, controlling presentation of the service-information page in the terminal;
• receiving second interaction information provided by the terminal through the data channel;
• and
• presenting the second interaction information in a predetermined form or using the second interaction information.

A non-transitory computer-readable medium having stored therein instructions that, when executed by a processor of a terminal configured to communicate with a device, causes the terminal to perform a calling method, the method comprising:

• establishing a data channel with the device for assisting a call, when the terminal is conducting the call with the device through a voice channel;
• and
• exchanging interaction information with the device through the data channel, wherein the interaction information is configured to assist a first user of the terminal and a second user of the device in coordinating and interacting when conducting the call, and wherein the exchanging of the interaction information with the device includes:
• receiving first interaction information provided by the device through the data channel;
• presenting the first interaction information in a predetermined form, wherein when the first interaction information includes a service-information page, the presenting of the first interaction information in the predetermined form includes:
• parsing the service-information page;
• and
• presenting the service-information page in a user interface;
• and
• transmitting second interaction information to the device through the data channel.
