Variable Value
Phone Action
phonecfg=get[&accounts=x][&dn
d=x][&fw=x]
Get firmware version, registration, DND or
forward configuration information.
The valid value of “x” is 0 or 1, 0 means you
do not need to get configuration
information. 1 means you want to get
configuration information.
Note: The valid URI is: http(s)://phone IP
address/servlet?phonecfg=get[&accounts
=x][&dnd=x][&fw=x]
Example:
http://10.10.20.10/servlet?phonecfg=get[&a
ccounts=1][&dnd=0][&fw=1]
Note
Yealink IP phones also support a combination of the variable values in the URI, but the
order of the variable value is determined by the operation of the phone. The valid URI
format is: http(s)://phone IP address/servlet?key=variable value[;variable value] .
Variable values are separated by a semicolon from each other. This method is not
applicable to SIP-T48G IP phones.
The following shows an example for deleting all entries from the call history list when
the phone is idle:
For T46G/T42G/T41P/T40P/T29G/T27P/T23P/T23G/T21(P) E2/T19(P) E2:
http:// 10.3.20.10/s ervlet?key=F1;F3;DOWN;DOWN;DOWN;OK;OK.
For CP860:
http:// 10.3.20.10/s ervlet?key=F1;OK;F3;DOWN;DOWN;DOWN;OK;OK.
For security reasons, IP phones do not receive and handle HTTP/HTTPS GET requests by
default. You need to specify the trusted IP address for action URI. When the IP phone
receives a GET request from the trusted IP address for the first time, the LCD screen
prompts the message “Allow Remote Control?”. You can specify one or more trusted IP
addresses on the IP phone, or configure the IP phone to receive and handle the URI
from any IP address.
You can use action URI feature to capture the phone’s current screen. For more
The variable value is not applicable to all events. For example, the variable value
“MUTE” is only applicable when the IP phone is during a call.
When authentication is required, you must enter
“p=login&q=login&username=xxx&pwd=yyy&jumpto=URI&” before the variable
“key”. xxx refers to the login user name and yyy refers to the login password.
