Troubleshooting
Problem
Solution
No audio is heard on the handset
when it is plugged into the PHONE
interface on the TEL1
Check that the TEL1 is on-hook so audio
is routed to the handset.
Check that the handset is plugged into the
PHONE interface, the telephone line is
plugged into the LINE interface, and check
that the phone line plugged into the LINE
interface is an analog phone line (POTS)
and not a digital line.
No loop current or line voltage is
measured on the Phone Settings
screen
If there are multiple TEL1 or TEL2 cards
make sure the correct phone line is
selected. On the TEL2, ensure you are
viewing the correct virtual telco channel
associated with the physical phone line.
Ensure sure the telephone line is plugged
in and active by plugging an optional
handset directly into telephone line and
seeing if dial tone is present.
