Table 129 Troubleshooting Telephone

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 VoIP SIP Settings screen properly configured.

I can access the

Internet, but

cannot make VoIP

calls.

Make sure you have the VoIP SIP Settings screen properly configured.

One of the PHONE lights should come on. Make sure that your telephone is

connected to the corresponding PHONE port.

You can also check the VoIP status in the Status screen.

If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you

can make a call using speed dial, there may be something wrong with the SIP

server, contact your VoIP service provider.

I cannot call from

one of the ZyXEL

Device’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 ZyXEL Device 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.
