Publication Date:  2014-10-30 Views:  44 Downloads:  0
Issue Description
customer reported that they want to develop the 3rd party to control TE30 but it can`t work.
Alarm Information
no alarm
Handling Process
As we know that for VCT terminal, the former version we can use http/telnet to develop the 3rd party(the newest version we can only use https). but for TEx0, we only have https to control. for the doc we can check<HUAWEI TEX0 Videoconferencing Endpoint HTTP API Reference Guide>.
for this case, customer reported that he can not control camera of TE30.
for us, we need to know what did customer do and which interface he used. so we ask him to select the packets and scenario.
1. customer said he use this interface:WEB_CtrlCameraOpeateAPI
and his command is {"camState": "remoteCam", "camAction": ”0”, "camPos": "5", "camSrc": "0"
}), 
2. customer feedback the packets of the process.

we found customer send 2/1/0 to the remote. then we check the doc we found that it`s incorrect parameter.
so we advice to change it into this string.
[2]Start tilting upward.
{"camState":"localCam","camAction":2,"camPos":255,"camSrc":0}
after ask customer changed this, the issue is solved
Root Cause
customer send the wrong string to TE30. so TE30 can`t response it.
Solution
after change the sending message, the issue solved.
Suggestions
Though we are not familiar with the 3rd party, but the diagnose way is same. we should know what did customer do and get some packets/traces, the issue will be easier.
