When the user presses the record key for the second time, the IP phone sends a SIP INFO 
message to the server with the specific header “Record: off”, and then the recording stops. 
Example of a SIP INFO message: 
Via: SIP/2.0/UDP 10.3.20.14:5060;branch=z9hG4bK175716007

URL Record 
When a user presses a URL record key for the first time during a call, the IP phone sends an 
HTTP GET message to the server. 
Example of an HTTP GET message: 
GET /URLRecord/record.xml HTTP/1.1\r\n 
Request Method: GET 
Request URI: /URLRecord/record.xml 
Request version: HTTP/1.1 
Host: 10.3.5.97:8080\r\n 
User-Agent: Yealink SIP-T46G 28.81.0.25 00:15:65:74:B1:50\r\n 
If the recording is successfully started, the server will respond with a 200 OK message. 
Example of a 200 OK message: 
<YealinkIPPhoneText> 
<Title> 
</Title> 
<Text> 
The recording session is successfully started. 
</Text> 
<YealinkIPPhoneText> 
If the recording fails for some reasons, for example, the recording box is full, the server will 
respond with a 200 OK message.
