3. The method according to claim 1 , further comprising:

sending, using the at least one processor, information indicating that the terminal is not able to use the instant messaging system to the terminal in response to determining the particular user identifier is not stored in the memory.

4. The method according to claim 3 , further comprising:

sending, using the at least one processor, information indicating the voice call of the terminal is to be placed on hold in response to determining the particular user identifier is not stored in the memory.

5. The method according to claim 1 , wherein the first message indicates that the terminal is able to use the instant messaging system.

6. The method according to claim 1 wherein,

the receiving the request receives the request via another server, and

the sending the first message sends the first message via the other server.

7. The method according to claim 6 , wherein the sending the first message sends information indicating that the terminal is not able to use the instant messaging system to the terminal via the other server in response to determining the particular user identifier is not stored in the memory.

8. A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a server, cause the at least one processor to:

receive a request to initiate communication over an instant messaging system based on a connected voice call of a terminal, the request including a telephone number of the terminal;

determine whether a particular user identifier of a user of the terminal is stored in a memory of the server based on the telephone number, the memory of the server storing one or more user identifiers in association with one or more telephone numbers, the one or more user identifiers being associated with the instant messaging system;

send a first message to the terminal based on the particular user identifier in response to determining the particular user identifier is stored in the memory, the first message indicating an identifier of an operator terminal or an identifier of the server as a sender of the first message;

send a request to the terminal based on the particular user identifier to add the identifier of the operator terminal or the identifier of the server as a contact associated with the instant messaging system; and

receive a second message from the terminal via the instant messaging system after the request is sent to the terminal, the particular user identifier being a contact of the identifier of the server in the instant messaging system when the second message is received from the terminal.

9. The non-transitory computer-readable medium according to claim 8 , wherein the instructions cause the at least one processor to receive the request when a hold duration of the voice call exceeds a determined time.

10. The non-transitory computer-readable medium according to claim 8 , wherein the instructions cause the at least one processor to send information indicating that the terminal is not able to use the instant messaging system to the terminal in response to determining the particular user identifier is not stored in the memory.

11. The non-transitory computer-readable medium according to claim 10 , wherein the instructions cause the at least one processor to send information indicating the voice call of the terminal is to be placed on hold in response to determining the particular user identifier is not stored in the memory.

12. The non-transitory computer-readable medium according to claim 8 , wherein the first message indicates that the terminal is able to use the instant messaging system.

13. The non-transitory computer-readable medium according to claim 8 , wherein the instructions cause the at least one processor to:

receive the request via another server; and

send the first message via the other server.

14. The non-transitory computer-readable medium according to claim 13 , wherein the instructions cause the at least one processor to send information indicating that the terminal is not able to use the instant messaging system to the terminal via the other server in response to determining the particular user identifier is not stored in the memory.

15. A server, comprising:

a memory storing,

computer-readable instructions, and

one or more user identifiers in association with one or more telephone numbers, the one or more user identifiers being associated with an instant messaging system; and

at least one processor configured to execute the computer-readable instructions to,
