Table 119   Troubleshooting Telephone 

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.
