When I make
Internet calls, the
sound quality is poor.
I cannot make
Internet calls, but it
worked yesterday.
PROBLEM POSSIBLE CaUSES POSSIBLE SOLUTIONS
1) There is too much simultaneous
data traffi c on your broadband
connection.
2) Your Internet Telephony Service
Provider’s Quality of Service is
based on a “best efforts” rather
than a guaranteed voice priority
method.
1) The gateway is not logged in at
the Internet Telephony Service
Provider.
2) The router is turned off.
3) The SIP server is down.
4) The Internet connection is down.
1) a) Reduce the amount of traffi c on
your broadband connection.
b) Sign up for a Quality of Service
agreement with your broadband
provider.
c) Order a connection with higher
speed from your broadband
provider.
2) Contact your Internet Telephony
Service Provider regarding ensured
voice prioritization across the
network.
1) Check that all cables are connected
properly, and check that power is
turned on, and then reset the gateway.
2) Turn on the router.
3) Contact your Internet Telephony
Service Provider.
