Yealink SIP-T48G User Manual

Basic Call Features
161
If the forward on code or off code is configured, the IP phone sends the corresponding code to
the server when a certain action takes place. For example, if you set the Always Forward on code
to be *71 (may vary on different servers), and the target number to be 1234. When you activate
Always Forward on the IP phone, the IP phone sends *711234 to the server, and then the server
will activate Always Forward feature on the server side, hence being able to get the right status
of the extension.
Call forward is configurable via web user interface at the path Features->Forward&DND.
Note
To configure the forward authorized numbers via web user interface:
1. Click on Features->Forward&DND.
2. Select Enabled from the pull-down list of Forward Emergency.
3. Enter the numbers in the Forward Authorized Numbers field.
For multiple numbers, enter a comma between every two numbers.
4. Click Confirm to accept the change.
When call forward is activated on the phone, the phone cannot forward incoming calls from the
numbers specified in the Forward Authorized Numbers field.
Note
You can also enter the SIP URL or IP address in the Forward to field. For more information on
using the SIP URL or IP address, refer to Placing Calls on page 134.
Call forward is local to the phone, and may be overridden by the server settings. Call forward on
code or off code may be different among servers. For more information, contact your system
administrator.
Forward authorized number is configurable via web user interface only.
