76 ADSL X5v User’s Guide
The person or persons you are calling may not be available. Try
again later. Or, if there is a chance you may have the wrong
number, go to the provider’s web site and check the directory.
Check if the person you are trying to call uses the same VoIP
service as you. If not:
• You will have to precede your call by dialing a code for that
person’s VoIP service. Ask the person you are attempting to
call for the code, or check the service provider’s web site for a
list.
• In some cases, there may not be a way to make direct VoIP
calls from your service to people subscribing to another VoIP
service. Check the web site, or email your provider.
When I try to make a VoIP call to a standard PSTN number,
the call doesn’t go through.
Make sure that:
• You have signed up for PSTN service with your VoIP service
provider. Contact your provider’s customer support
department if necessary.
• You are dialing according to the guidelines your service
provider gave you. Your provider’s web site should provide
instructions and examples. For instance, you may need to dial
local calls as though they were long distance. Or, you may need
to dial a call within your country as though you were calling
from outside the country—beginning with an international
prefix such as 00, followed by the country code, city code or
area code, and local number.
• You aren’t taking too long between digits when you dial a
number. If you take a very long time, the X5v may register that
you have completed dialing before you are through. If this is a
possibility, hang up and try again.
