I cannot dial out.
• First try all the suggestions above.
• Make sure you have a dial tone before dialing. The corded handset might
take a second or two to connect the deskset and produce a dial tone. This is
normal. Wait an extra second before dialing.
• Make sure the deskset is set to the correct dial mode (pulse dial or tone dial)
for the service in your area. Refer to Dial mode in the online complete user’s
manual to set the dial mode.
• If the other telephones in your building are having the same problem, contact
your telephone service provider.
I cannot switch a call from the deskset to the UP407 cordless handset.
• Make sure the system has only one line operating. You cannot switch the call
from the deskset to your UP407 cordless handset if there is more than one
telephone line in operation.
The deskset obtained an IP from the Ethernet switch or router but is not
connected to the console.
• You have to enter the name of the console and assign an extension
number to this deskset after an IP is obtained. Refer to Deskset
installation on page 9 for details.
• Make sure both the console and deskset are directly connected to the
same Ethernet switch or router.
