Please note:
If port forwarding is activated on your router
for the ports that have been registered as the
SIP port (Standard 5600) and the RTP port
(Standard 5004), then it makes sense to switch
off DHCP and assign the phone a static IP
address (otherwise you may not be able to
hear the other party during VoIP calls), see
page 25.
Please note that the IP address and subnet
mask depend on the router's address block.
You must also enter the default gateway and
DNS server via the Web configurator
(page 26). The IP address for the router is gen-
erally entered here.
