Signing In

After the sign-in is performed by the interface in Signing In, the parameters related to the sign-in are stored in the request content and are identified in JSON format. The following is an example:
```
{"password":"xxxxxxxx","phonenum":"6001"}
```
In the preceding information, the password field indicates the sign-in password, and the phonenum field indicates the phone number of the agent.
After the agent successfully signs in, the following information is displayed:
```
{"retcode":"0","msg":"",result:{"workno":"6001","mediatype":"TTT"}}
```
In the preceding information, the mediatype field indicates whether the agent successfully signs in to the CTI server, WebM, and MailM. T indicates successful sign-in, and F indicates sign-in failure. Voice and video call businesses can be handled only after the agent successfully signs in to the CTI Server. Text chat businesses can be handled only after the agent successfully signs in to the WebM. Currently, the agent cannot sign in to the MailM.
If the agent fails to sign in and the value of retcode is 100-002, the agent has signed in and the interface in Forcibly Signing In is invoked to forcibly sign in.
