Yealink SIP-T48S with SwyxWare
1 Phone model
In order to use extended functionality, the "Feature Pack for Certified SIP Phones"
license is required from the administrator. In addition, each device must be set up initi-
ally via Swyx Control Center before operation, see also
latest.version/web/Swyx/en-US/index.html#page/help/chap_deskpho-
nes.12.1.html#.
For information on the characteristics and operation of the Yealink SIP-T48S, see the
manufacturer's documentation (support.yealink.com).
Please note that the operation and selection on the Yealink SIP-T48S is done via touch dis-
play. It may be necessary to first press a key when the phone is in standby mode before
taking any action.
2 Activate terminal device
It is required to activate the terminal device on first connection if your administrator has
selected the "Activation required on certified phones" option in the server configura-
tion.
Yealink desk phones are configured in English by factory default. After connection to the
SwyxServer, the language is automatically changed to the standard server language.
1. Connect the phone to the power supply and to the network via the "Internet" port using
a LAN cable. Alternatively, the phone also supports connection via PoE (Power over
Ethernet) according to the IEEE 802.3af standard.
3 Logging on and logging off from a terminal device

If you connect the terminal device to the network before your administrator has entered
the MAC address of the terminal device in Swyx Control Center, the login prompt may not
appear on restart. The device will then not be recognized by SwyxServer.
After the required configuration has been made, you can restart the device and the logon
prompt via "Reboot", or by disconnecting the device from the network for a short time.

In the "Password" field, enter the 8-digit activation key you received from your adminis-
&123

The telephone connects to the SwyxServer. After completion of the configuration,

your user name is shown on the display. The telephone can be used immediately
and configured if necessary.

by disconnecting it from the power supply for 10 seconds.
