Possible causes
The configuration of
the TS-850i is
not complete.
The base has not been
reset after you saved
the configuration.
The router uses
port forwarding.
The router blocks
Internet telephony.
Possible solutions
Check that you have
configured your TS-850i
properly. Go to the
TalkSwitch management
software and check the
configuration. For more
information, contact
your Internet
Telephony Service
Provider.
Reset the base and
allow the base two
minutes to log in at
your Internet
Telephony Service
Provider.
Check that you have
configured your router
so that it always
assigns the same IP
address to your TS-
850i's MAC address
when using port
forwarding. Otherwise
incoming traffic is
probably not forwarded
to your TS-850i. For
more information,
check your router's
user guide.
Try disabling STUN.
Open the Internet
settings menu, choose
STUN mode, and select
Disabled. Reset the
base. For more
information, contact
your Internet
Telephony Service
Provider.
