PROBLEM CORRECTIVE ACTION
The telephone port
won’t work or the
telephone lacks a
dial tone.
Check the telephone connections and telephone wire.
Make sure you have the Voice SIP Settings screen properly configured.
I cannot call from
one of the
Prestige’s phone
ports to the other
phone port.
You cannot call the SIP number of the SIP account that you are using to make a
call. The Prestige generates a busy tone and does not attempt to establish a call
if the SIP number you dial matches the outgoing SIP number of the phone port
you are using.
For example, if you set Phone 1 to use SIP account 1 and set Phone 2 to use SIP
account 2, then you can use Phone 1 to call to SIP account 2's SIP number or
Phone 2 to call to SIP account 1's SIP number.
