SIP registration failed!

Your personal data for registering with the VoIP provider may have been entered incom-
pletely or incorrectly.

Check your entries for Username,
particular, check your use of upper and lower case.
To do this, open the following menu on your handset:

The server address for the VoIP server has not yet been entered, or has been entered
incorrectly.

Start the phone Web configurator.

Open the following Web page:
¤
Edit the server address where necessary.
Please note:
– STUN (Simple Transversal of UDP over NAT) should always be deactivated on your base station
phone (default setting), and a port number from the block 5056 – 5071 should be set for the local
SIP port (default 5060).
Check these settings if you cannot hear the other caller or if you cannot be reached.
You can set STUN mode (page 94) and the local SIP port (page 102) via the phone Web
configurator.
– If port forwarding is activated on your router for the ports that have been registered as the SIP port
(default 5060) and the RTP port (default 5004), it makes sense to assign the phone a static IP
address (otherwise you may not be able to hear the other party during VoIP calls), see page 59.
Please note that the IP address and subnet mask depend on the router's address block.
You must also enter the standard gateway and DNS server. The IP address for the router is
generally entered here.
You will find other messages and possible measures in the "Questions and answers" section
on page 113.
Belt clip and headset
By using a belt clip and headset (optional) you can easily make your handset a constant
companion.
Attaching the belt clip
There are notches for attaching the belt clip on the side of the handset at approximately
the same height as the display.
¤
Press the belt clip onto the back of the handset so that the protrusions on the belt clip
engage with the notches.
The tongue of the belt clip must face the battery compartment.
Connection socket for headset
You can use headsets with jack connectors. The following models have been tested and are
therefore recommended: HAMA Plantronics M40, MX100 and MX150.
The transmission quality of other models cannot be guaranteed.
